Blowing Up Mountains: Destroying the Environment for Coal
 
20:30
Massive corporations are blowing up mountains and creating environmental ruins in West Virginia. All this devastation, just to extract some coal. We went to West Virginia to investigate mountain-top removal -- which a way of extracting coal from deposits under mountains. Instead of drilling into the mountain and sending men underground to take out the coal in the traditional way, they just take the whole top of a mountain off.

POWERING THE WEST IN BLM COAL COUNTRY
 
03:59
Coal mining is an important use on public lands and helps meet America’s energy needs. It is a strong economic driver both locally and nationally – for many rural communities, this is particularly true. The Trapper Mine near Craig, Colorado plays a vital role in the town’s economy, providing good paying jobs for members of the local community. BLM staff in the Little Snake Field Office work closely with mine operators to ensure coal development takes place in an environmentally responsible manner.

THANATIA -- The Destiny of the Earth's mineral resources
 
05:18
Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today. This book presents a cradle-to-cradle view of the Earth's abiotic resources through a novel and rigorous approach based on the Second Law of Thermodynamics: heat dissipates and materials deteriorate and disperse. Quality is irreversibly lost. This allows for the assessment of such depletion and can be used to estimate the year where production of the main mineral commodities could reach its zenith. By postulating Thanatia, one acquires a sense of destiny and a concern for a unified global management of the planet's abiotic resource endowment. The book covers the core aspects of geology, geochemistry, mining, metallurgy, economics, the environment, thermodynamics and thermochemistry. It is supported by comprehensive databases related to mineral resources, including detailed compositions of the Earth's layers, thermochemical properties of over 300 substances, historical energy and mineral resource inventories, energy consumption and environmental impacts in the mining and metallurgical sector and world recycling rates of commodities.

Protection Against Radioactivity in Uranium Mines 1969 US Bureau of Mines
 
25:12
This film from the United States Bureau of Mines presents general descriptions of the hazards of radon daughters in uranium mines, and outlines the environmental control, principles and procedures for mitigating the hazard. Scenes of underground mines show the origin and reason of the hazard, and various methods of ventilation are shown on how to correct the condition. Uranium mining occurred mostly in the southwestern United States and drew many Native Americans and others into work in the mines and mills. Despite a long and well-developed understanding, based on the European experience earlier in the century, that uranium mining led to high rates of lung cancer, few protections were provided by employers or government for US miners before 1962 and their adoption after that time was slow and incomplete. Some US officials and scientists advocated ventilation requirements in US mines as a proactive, preventative measure during the 1950s, on the basis of their knowledge of European experience. Duncan Holaday, an industrial hygienist with the PHS, has generally been recognized as the most prominent advocate for ventilation. He led the effort to obtain measurements of radon in the mines, and he used the data to argue forcefully within the government that ventilation would be effective and was feasible. His arguments achieved only limited success, as there was government resistance to requiring ventilation and his views were not made public at the time. The Atomic Energy Commission (AEC) was an obstacle. In the late 1940s, controversy erupted in the New York Operations Office over the hazards from beryllium and uranium mining. The AEC wrote worker health requirements in contracts with companies that handled beryllium. After conflicting recommendations from staff, it chose not to establish such requirements for uranium. It claimed to lack legal authority, but it did not explain the legal difference between uranium and beryllium. The AEC did not lack knowledge: records of a January 25, 1951, internal meeting of AEC and PHS staff reveal that, on the basis of early measurements, they believed that radon was present in levels that would cause cancer and that ventilation could abate the hazard. Public acknowledgment of this problem was apparently squelched. For instance, Hueper, the scientist who wrote the 1942 review and who was then at the National Cancer Institute, was forbidden to speak in public about his concerns about the health hazard of radon in uranium mines. It is reported that he was even forbidden to travel west of the Mississippi, lest he say too much to the wrong people. The resulting high rates of illness among miners led in 1990 to passage of the Radiation Exposure Compensation Act. For more details, see the outstanding article, The History of Uranium Mining and the Navajo People, in the Sept 2002 American Journal of Public Health at http://www.ajph.org/cgi/reprint/92/9/1410 .

Mining Matters in your Everyday Life
 
04:19
This video by the Colorado Mining Association presents an informative and educational video on how mining matters to each and every one of us in our every day life, not just in Colorado but around the world. Many do not realize that our modern society relies on mining for many of the products and comforts we enjoy including such electronic devices such as computers, cell phones, MP3 Players, home appliances, and medical diagnostic equipment to name a few . Many of the facets of the lifestyle we enjoy in Colorado would not be possible without mining, including ski lifts, roadway anti-skid treatments, mountain bikes, , as well as the heat , shelter and electricity needed to survive a long cold mountain night. Colorado is a major producer of molybdenum (called moly for short) which is used in stainless steel, cars, lubricants, and light bulbs. Moly is also used in automotive catalytic converters, to help keep our environment clean. Mining provides for personal health care products you use every day such as cosmetics, toothpaste, deodorant, calamine lotion, baking soda, and your sunscreen! 72% of Colorado's electricty is provided by clean, abundant coal. Coal provides 50% of the electricity nationwide. Colorado coal is low in ash and sulfur; therefore, it is considered "clean coal" Modern methods of filtering and scrubbing coal plant stack emissions provide for cheap and affordable energy to energize our economy and meet the affordable energy costs with little emissions into our environment. Alternative energy such as wind, solar , hydro and geothermal options become a feasible component for fulfilling our Nations' energy needs. Colorado is pursuing an aggressive alternative energy program which depends on the mining industry to provide the raw materials to build the solar panels, wind turbines, hybrid cars, and transmission line infrastructure required to meet the demands of these future programs. Bio-Fuel production, and modern agriculture in general would not be possible without the fertilizer and pest control products which rely on mining for some ingredients. Many do not realize that Colorado uranium is used around the world to fuel clean, efficient, zero emissions nuclear energy facilities in both the industrial and military sectors. Modern mining is conducted without damaging the environment. Any surface disturbances are restored back to their natural condition, typically providing an improved animal habitat. Modern Mmning is environmentally sound and actually safer than most other occupations. You are far more likely to be injured working in the retail, construction or transportation industries than working in a mine, above or below ground. Colorado miners are typically persons who love and actively protect their fragile mountain environment in which they live and work. They usually live in close proximity to the mines and go above and beyond any environmental or safety regulations, not only in their stewardship of environmental protection, but for the protection of their families, homes, co-workers and community in which they live.

Mining, Ecological Engineering and Metals Extraction for the 21st Century
 
56:03
Speaker: Margarete Kalin, Research Director and President of Boojum Research Ltd. This webinar is an introduction to a recent contribution on sustainable mining, remediation and metal extraction to the Oxford Research Encyclopedia of Environmental Science, Problems and Solutions. Co- authors are M. Kalin, Michael P. Sudbury and Dr. Bryn Harris. The mining industry developed in an age when resources, space and water appeared limitless. A paradigm shift is needed in mining, remediation and extractive metal processes. Human’s insatiable appetite for metals is estimated to produce annually 20 billion tons of waste rock and tailings, covering about 1000 km2 of land. The annual consumption of fresh water is estimated to be about 80 10-9 tons, most of it will be contaminated. A collision course is on the horizon, given shortages of water and arable land and the ever-increasing global population. The key to a solution to the present un-sustainable environmental management practices lays in ecologist’s view of mining wastes as extreme primordial environments. Natural recovery processes can be supported through ecological engineering measures. This starts with exploration and through to operations, ending with decommissioning. By providing physical and chemical support to promote existing ecological processes within the wastes, we can alter the surface of minerals, thereby decreasing contaminant generation and reducing the volume of drainage by promoting run-off. Supporting the growth of indigenous biota leading to increased agglomeration of contaminant on the cell surfaces and upon death the biomass with its contaminants sinks to the sediments. Through bio-mineralization in the sediment, the metals are stabilized, potentially generating in the long-term biogenic ore bodies. All processes are implemented within the mine waste and water management area. Brief examples are given of: -Acid Reduction Using Microbiology through sediment construction; -Alterations of the mineral surface on waste rock reducing sulphide oxidation by effective nutrient supply carried into the wastes by rain and; -Biological polishing “in alkaline and acid mine waste water by a pH adjustment (if needed) and adjusting nutrient imbalances; -Estimates of reductions in waste generation using efficient metals extraction processes. Boojum’s multidisciplinary team of scientists guided by experts of the industry, has laid the foundation for ecological engineering in publications and field demonstration projects. Moving forward we need to evaluate these demonstration project to use the results to build confidence in the approach of ecological engineering, only then can we achieve the paradigm shift needed for the future of the industry. Learn about the speaker: Margarete Kalin is Research Director and President of Boojum Research Ltd. The R& D firm in collaboration with mining companies, the Canadian government and research organizations , has developed and demonstrated an ecological toolkit, that leads to a self-sustaining decommissioned mine waste and water management area. More than 100 scientific publications, numerus chapters in technical books documenting the natural processes and approximately 150 project reports are available on line at http://biblio.laurentian.ca/boojum. Margarete received the Noranda Award for Outstanding Achievements in Land Reclamation from the Canadian Land Reclamation Association and the Teck-Cominco Environmental Award from the Canadian Institute for Mining and Metallurgy (CIM). She was nominated in 2005 as a Distinguished Lecturer by the CIM. She is certified as a QEP (Qualified Environmental Professional ) by the Institute of Professional Environmental Practice and as a Senior Ecologist by the Ecological Society of America. She has been Adjunct Professor at several Canadian universities.

Global Climate Change Policy - Extractive Industry Impacts and Response
 
01:04:03
Jeff Hopkins, Principal Adviser for International Energy and Climate Policy at Rio Tinto, presented on October 29, 2013 as part of the AEDE Applied Economics Seminar Series. His presentation focused on climate change policy as experienced by an international mining company. This seminar was sponsored by Ohio State's Environmental Policy Initiative. Dr. Hopkins leads policy engagement in the U.S. and Canada for Rio Tinto and works with a globally-distributed corporate team as well as external affairs and environmental specialists who work on-site at Rio Tinto mines and businesses. Rio Tinto is the largest diversified mining company in the U.S. and the second-largest mining company in the world, with major operations producing iron ore, copper, aluminum, uranium, thermal and metallurgical coal, gold, and industrial minerals. As part of their mining, refining, and smelting of these metals and minerals, Rio Tinto emits 41 million tons of GHG emissions per year. Over 70 percent of these GHG emissions occur in places where carbon is regulated through a price-based scheme such as cap and trade or a carbon tax. Dr. Hopkins' policy education and advocacy work on behalf of Rio Tinto at the national and regional levels, often in collaboration with the larger business community and environmental NGOs, is based on extensive experience in scheme development and implementation. Prior to working for Rio Tinto, Dr. Hopkins was a policy analyst and chief economist for the United States House of Representatives Committee on the Budget, and before that for USDA's Economic Research Service. Dr. Hopkins received a PhD from AEDE in 1998, and was a Peace Corps Volunteer in Guatemala from 1987-1989.

What is GOLD PLACER CLAIM? What does GOLD PLACER CLAIM mean? GOLD PLACER CLAIM meaning - GOLD PLACER CLAIM definition - GOLD PLACER CLAIM explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In the United States, a placer claim grants to the discoverer of valuable minerals contained in loose material such as sand or gravel the right to mine on public land. Other countries such as Canada, Mexico, and Australia grant similar rights. In the United States, the valuable mineral in a placer claim is almost always gold, although other nations mine placer deposits of platinum, tin, and diamonds. Another type of mining claim is a lode claim. A mining claim allows some security of tenure for the owner, providing an incentive to invest time and money developing the deposit. Mining claim laws vary from state to state, but claims staked over federal minerals follow federal mining law. Federal minerals are managed by the U.S. Bureau of Land Management (BLM). Mining claims staked under either State or federal laws (state claims may only be staked on state-owned and managed lands; federal claims may only be staked on minerals owned by the federal government) are limited to lands available for claim staking at the time the claims are staked. Thus, if the land is not available for mineral entry (example: withdrawn due to its status as a park or refuge), then the claim is said to be invalid ab initio. An additional requirement is "Discovery", which follows the "Prudent Man Rule." This means that a sufficient indication of valuable mineral(s) would encourage a "Prudent Man" to further invest time and money developing the deposit towards the goal of mining it. The holder of a mining claim does not own the surface, the water, or even the rocks and gravel. A mining claim grants the holder with the preferential right to extract the valuable minerals within the claim, and for uses incident to that goal, such as prospecting, exploration and development. Gold mining is one of the most common uses for the staking of mining claims. In Alaska, state mining claims may be up to 160 acres (0.65 km2), and there is no distinction between lode or placer claims. The boundaries of the claim must follow the 4 cardinal directions, with an exception being adjustments for existing valid claims. "Claim jumping", which happens to this day, is a case where one person overstakes the claims of another. This results in civil action, and sometimes violence. Claims staked on Federal-managed lands fall under Federal rules. Typically, the claim size is limited to 660'x 1320', or 20 acres (81,000 m2). The claim must be either placer or lode, and the discovery point must be clearly marked. The claim staking procedure includes setting a monument (a post of at least 3" in diameter and at least 3' visible above the ground, or a rock monument at least 3' in height) at the NE corner of the claim. This is known as the Number 1 corner, and it is here that the claimant places the location notice. Three additional monuments, one at each corner of the mining claim, must be set, numbered in a clockwise direction. Copies of the claim documents must be filed in the local offices of the land managers, and filing fees paid. This must be completed within 45 days of the staking. In addition, fees for annual rental, filing, and work (or payments in lieu of labor) to fulfill requirements of "annual labor" must be completed by the deadlines set by the regulations in order to hold the claim. Failure to meet any of these requirements will result in a declaration of abandonment, and the claim cannot be restaked by the original locator or a successor in interest for one year from the date of abandonment. During this time, the claim may be relocated by others.

Secretary Salazar's remarks on June 20, 2011 from the Grand Canyon
 
12:22
PROPOSED MINERAL WITHDRAWAL NEAR GRAND CANYON NATIONAL PARK What was announced on June 20, 2011? Secretary of the Interior Ken Salazar announced his decision to make an emergency withdrawal for six months of approximately 1 million acres of federal lands near Grand Canyon National Park from hard rock mining claim location and entry under the 1872 Mining Law while the Department continues to evaluate whether to withdraw these lands from new mining claims for 20 years. Valid existing claims are not affected by this announcement. What are the next steps? A Public Land Order making an emergency withdrawal of six months will be published in the Federal Register within the next week. A final EIS is expected to be released to the public in the fall of 2011. Why is this action of an emergency withdrawal necessary? On July 21, 2009, the Department published a notice in the Federal Register of a proposed withdrawal of approximately 1 million acres of federal locatable minerals on both BLM and Forest Service lands in northern Arizona from location and entry under the 1872 Mining Law and that action began a two-year temporary segregation period that expires on July 20, 2011. This action is necessary to prevent the lands from opening to new mining claim location and entry under the 1872 Mining Law when that segregation expires. What is the preferred alternative? The preferred alternative that will be included in the final Environmental Impact Statement (EIS) is the full proposed withdrawal of approximately 1 million acres of BLM and Forest Service lands located near Grand Canyon National Park from mining claim location and entry under the 1872 Mining Law for 20 years, subject to valid exiting rights. The selection of a preferred alternative is required as part of the development of an EIS under the National Environmental Policy Act. The EIS to analyze a proposed withdrawal of these lands of up to 20 years is currently under development and is expected to be completed in the fall of 2011. Has there been public input? Over 295,000 public comments were received during the public comment period on the EIS, which included an initial period of 45 days and was extended 30 days to allow for additional public comment. The interagency team worked with eleven other cooperators and held thirty-one consultation meetings with tribes. Who are the cooperating agencies? U.S. Forest Service; National Park Service; U.S. Fish and Wildlife Service; U.S. Geological Survey; Arizona Game and Fish Department; Arizona Geological Survey; Arizona Department of Mines and Mineral Resources; Arizona State Land Department; Hualapai Tribe; Kaibab Band of Paiute Indians; Coconino County, Arizona; Mohave County, Arizona; Kane County, Utah; San Juan County, Utah; and Washington County, Utah. What lands are affected by today's announcement? These lands are within portions of the Grand Canyon watershed next to Grand Canyon National Park and contain significant environmental and cultural resources as well as known uranium deposits. The Grand Canyon National Park is an iconic American landscape and World Heritage Site and draws 4.4 million visitors each year, is home to numerous rare, endemic and specially protected plant and animal species and contains vast archeological resources and sites of spiritual and cultural importance to American Indians. The Colorado River and its tributaries that flow through the watersheds of Grand Canyon National Park supply water to agricultural, industrial, and municipal users, including the cities of Tucson, Phoenix, Las Vegas, Los Angeles, and San Diego. What is an emergency withdrawal? During an emergency withdrawal, like a temporary segregation, the location of new hard rock mining claims under the 1872 Mining Law would be prohibited, however ongoing or future mining exploration or extraction operations on valid pre-existing claims could continue. The temporary segregation expires on July 20, 2011. Does this announcement affect oil, gas, coal, or other non-hard rock energy resources in the proposed withdrawal area? No. How many mining claims are there? At the time of the proposed withdrawal and temporary segregation, 10,600 hard rock mining claims existed. Today, approximately 3,500 claims remain. The emergency withdrawal will help maintain the status quo until a final decision is made on the proposed withdrawal. Where can I go to find out more information?

The State of Mining Today
 
01:12:22
The Mt. Polley tailing dam tragedy in BC took place in August 2014, spilling 25 million cubic meters of toxic waste. On November 5, Brazilians commemorate the 3rd anniversary of an even bigger catastrophe at Mariana, Brazil, when a reservoir of toxic mine waste collapsed, killing 19 people, spilling 32 million cubic meters of waste, and creating a toxic tsunami down the 650 km Rio Doce to the Atlantic. The circumstances leading to the socio-environmental catastrophes and the responses to them by mining companies, governments, and civil society tell us a lot about the state of mining today. The issues range from corporate impunity, to dangerous practices in mine waste management, to regulatory capture of governments by the mining industry, and to mining on Indigenous and Afro-descendant lands. Moderated by Liisa North, co-editor of Community Rights and Corporate Responsibility. Presentations by: * Judith Marshall, author of a comparative study on Mt. Polley and Mariana - Tailings dam spills at Mount Polley and Mariana: Chronicles of Disasters Foretold; * Matt Corbeil, researching mining industry lobbying in Ontario, author of "Why We Shouldn’t Pay $1-Billion for the Ring of Fire"; * Joan Kuyek, founding member of MiningWatch Canada and author of a new book entitled Putting Mining in its Place (forthcoming).

Uranium Mining in US and Canada in the 1970s
 
08:51
Physically removing the rock ore generally involves either open-pit mining or underground mining. Milling is the process that removes uranium from the ore, which is mostly obtained in open-pit and underground mines. Once at the mill, the ore is crushed and ground up, and treated with chemical solutions to dissolve the uranium, which is then recovered from the solution. Tailings are the wastes from the millings processes and are stored in mill tailings impoundments, a specially designed waste disposal facility. Since 1979, when uranium mine workers began being diagnosed with lung diseases, such as cancer, regulators have gradually tightened controls and mandated improved uranium mining practices. Recently, officials also have become concerned with the broader impacts of uranium mining on public health and the environment. Workers are directly exposed to the radiation hazards of uranium mines. Uranium mining also releases radon from the ground into the atmosphere. Mines and mining waste can release radionuclides, including radon, and other pollutants to streams, springs, and other bodies of water. Federal and state agencies have established pollutant discharge limits and drinking water standards, and continue to monitor these sites for public safety. Uranium mine waste from operations that closed before the mid-1970s are of particular concern. In many cases, these mines remain unclaimed and the waste is still piled near the mine. Weathering can lead to radioactive dust that is blown by the wind and the seepage of contaminants into the surface and groundwater. There are also cases of unclaimed uranium mine waste being used for house construction, which creates significant radon and radiation hazard for inhabitants. For more information on the hazards of uranium, go to USEPA website http://www.epa.gov/radtown/basic.html . This is clipped from the late 1970's BBC Production, Energy From The Crust, showing uranium mining activities and equipment and including footage from the following uranium mines: Schwartzwalder Mine, Near Boulder, Colorado King Solomon Mine near Uravan, Colorado and the Key Lake Mine in Saskatchewan, Canada.

Snowbird Clean Up Your Mine Tailings - Yankee Mine. Globe Mine
 
02:56
AMERICAN FORK CANYON, Utah County -- Debris from the tailings from more than 100 abandoned mines in the north fork area above Tibble Fork Reservoir has already pushed the mineral content in the American Fork River beyond acceptable water quality limits. U.S. Forest Service officials have consequently called in a hazardous materials expert, Ted Fitzgerald, to conduct an expensive cleanup and reclamation operation that's just a step below being classified as a Superfund site. "We're looking at a major reclamation effort in the canyon," said Fitzgerald, on-scene coordinator for the American Fork Canyon Hazmat Project. He said the effort was designated in 1993 by the Environmental Protection Agency as a Comprehensive Environmental Response, Compensation and Liability Inventoried Site. "That's in the same category as a Superfund site," he said. It's also legally necessary to comply with the stipulations in the Clean Water Act passed in 1972, he said. Targeted as the primary pollution sites are the Pacific Mine, the Globe Mine, the Bog Mines, the Yankee Mines and the area of Dutchman Flat. The Bog Mine soil samples show high levels of both lead and zinc. The Yankee Mines in the Mary Ellen Gulch area show a high level of both lead and zinc. The Pacific Mine showed a higher level of arsenic than recommended for human consumption, as well as lead, in four out of four fish tested. But there are more than 100 known mines in the canyon north fork of the American Fork Mining District -- mines left from an era that didn't yet recognize the need to protect fragile environments for future generations. The Pacific Mine site is the worst offender, but the Globe Mine is located almost directly on the stream, the Bog Mines are not far, and the other mines are releasing effluent material including a precipitate composed of iron and copper known as "Yellow Boy" that is staining the nearby soil. "It's good that it's here instead of into the stream," Fitzgerald said. From 1871 to 1876, more than $2.5 million in gold, silver and various ores were taken from the canyon mines by early miners who made quick money on their claims. The heyday was largely from 1870 through to 1912, with some renewed activity continuing into 1945. Most serious mining stopped in the 1930s, although Fitzgerald said some mines are occasionally worked. The metals, some of which are ground into fine grit by the milling process, wash out of the tailing piles and into the streams. Tiny organisms -- known as macroinvertebrates -- then absorb the metals, some of which are toxic. Since the macroinvertebrates are the main source of food for fish in the local water, the fish are left with less to eat and what they consume is heavily laced with metals. Cutthroat and brown trout samples collected in August showed high concentrations of the metals, especially arsenic and lead. Beaver dams on the river help some because the metals are collected by the natural compost. But when the streams and rivers run high, the metal components wash out and back into the water supply. Fitzgerald said culinary water for the downstream communities is not affected, but ground water in the canyon is at risk and the situation is unhealthy overall for the canyon environment. "Macroinvertebrates are one measure of an environment's health," he said. Previous owners and operators of the various mines are ultimately responsible for the costs of cleanup, which could run into the hundreds of thousands of dollars. Even the tailings on forest land or public property will be traced back to the mine of origin and the appropriate owner or operator will be billed where that's feasible. Fitzgerald said responsible parties, including corporations and descendants of mine claimants, are currently being contacted and will be told what they'll be expected to do. Affected governmental agencies, such as the Health Department, will be asked to join in to form a partnership to oversee the reclamation, Clark said. The public will be further informed about the situation within the next couple of weeks and some restrictions may go into effect such as limiting the four-wheeler activity near some of the tailings. Public reaction will be measured and if needed, public hearings will be scheduled before reclamation begins. The reclamation effort is expected to start within the next year and to be completed in October 2002. The leaking piles will be isolated. A series of man-made "cells," or artificial wetlands, will be constructed below the tailings and designed to capture the silt and metal before it enters the mainstream.

Two Guatemalans picked up for illegal gold panning
 
01:53
For the latest news across Belize, visit: http://edition.channel5belize.com/ Two Guatemalan men are serving eight months in jail for illegally entering Belize, specifically the Chiquibul National Park, to mine for gold. The joint work of Police, Belize Defence Force and Friends for Conservation and Development personnel a week ago on November twenty-fifth led to the capture of Anibal Qui-ix Cucul of Monte Los Olivos, Petén, and Jose Amilcar Garcia Morales of Huite, Zacapa, Guatemala, who were convicted in Belmopan Magistrate’s Court on Wednesday. It is uncertain if the Mining Unit will further charge them for extracting minerals without a permit. F.C.D. is once again warning of environmental impacts in the area as a result of the gold panners’ actions, although despite the presence of a conservation post in the area, the constant moving around makes it difficult to track offenders. News Five spoke to its executive director, Rafael Manzanero, today.

Currently they are leaching Cell One with water only as Cyanide breaks down with water and sunlight. Ore on Cell One is from the Goldspring Phase One era when ore was crushed to 5-minus to 4-1/2-minus. Minus Sizing: means crushed gravel will pass through heavy metal screens with square openings/apertures of 5 inches and 4-1/2 inches - only ore less than 5 inches will pass through the "5-Minus" square holes. Larger ore will move on the shaking screens to a trough that recirculates the larger ore back to the crusher to be further reduced until it can pass through the 5 inch or 4-1/2 inch screens. Ore that large may have had a low efficiency of leaching, hence gold may still be in the ore. If the ore is crushed to a smaller "Minus" determined by McClellan, then cyanide leaching may claim more of the gold left behind. Studies are being conducted to determine if it is worthwhile to reprocess the large size ore. It had an average content of 0.04 OPT Gold (Au). Approximately in 1-2 months they will know for sure what to do with ore on Cell One. Sprinkling with Barren Solution is with either Misters or Drippers. Drippers are better for the Hartford Complex as they provide a more consistent coverage. Visitor perceives Cell One as a large heap. A 1000th of a percent - an approximate ratio of cyanide to water. Cyanide does not leach free gold, therefore a "Cut-Off Grade" determines whether ore is sent to grinding mill or leach pad.

Ellis Martin Report with Ross Orr of BacTech Environmental
 
08:32
In this broadcast of The Ellis Martin Report, Ellis reports from Toronto where he attended PDAC, the Prospectors and Developers Association of Canada, the largest mining conference in the world. Join him for a conversation with Ross Orr, the President and CEO of BacTech Environmental Corporation, trading on the CNSX under the symbol BAC. BacTech is a pioneering, environmental technology company that has developed and commercialized a proprietary technology to remediate highly toxic tailing areas resulting from abandoned mining operations. BacTech's core technology, called "bioleaching", employs naturally-occurring bacteria, harmless to both humans and the environment, to oxidize the sulphide materials left behind after years of mining. The tailings may contain ores and related materials contaminated by arsenic and other substances that are poisonous to humans and animals, as well as harmful to the local environment. The sulphides in the tailings react (oxidize) with the atmosphere to create an acidic solution called acid mine drainage (AMD), which leaches into the surrounding area over time. BacTech's bioleaching process can stabilize these toxins from minerals and prevent additional harmful AMD. The technology provides a "Garden of Eden" environment for the bacteria to thrive and multiply and permits them to achieve in 6 days what would normally take 20 years to occur naturally. http://www.ellismartinreport.com http://www.bactechgreen.com contact: martinreports.com

Energy and Growth: Facts and Consequences
 
01:28:24
Economic growth depends critically on access to reliable energy. However, in much of the world, connectivity remains low, supply in connected areas is unreliable, and, at the same time, pollution and carbon emissions are on the rise. Professor Greenstone will explore some of the key trends that are shaping energy in the developing world and outline some solutions to their energy challenges. Michael Greenstone is a Research Programme Director (Energy) at the International Growth Centre (IGC), the Milton Friedman Professor of Economics in the department of economics at the University of Chicago and director of the Energy Policy Institute at Chicago (EPIC). Kaikaus Ahmad is the Additional Secretary from the Power Division in the “Ministry of Power, Energy and Mineral Resources” in the Government of Bangladesh. He has a PhD in Public Policy and Political Economy and an MA in Development Economics. His academic and civil service career magnetized him towards interdisciplinary subjects, and issues relating to poverty, economic development, governance, global interdependence, and institutional development always intrigues him. Mohammad Irfan Elahi is Chairman of the Planning and Development Board for the Government of Punjab. He is responsible for capital investment planning for the provincial government of Punjab, as well as planning for economic growth. He also helps coordinate various Government line departments in achieving development objectives. Sanjay Singh is Secretary to the Chief Minister for the Government of Bihar and Managing Director of Bihar State Power Transmission Co. Ltd. Before moving to the CM office, he served as District Magistrate of Patna. Robin Burgess is Founder and Director of the International Growth Centre. The International Growth Centre (@The_IGC) aims to promote sustainable growth in developing countries by providing demand-led policy advice based on frontier research. Based at LSE and in partnership with Oxford University, the IGC is initiated and funded by DFID. This public lecture is part of Growth Week 2014 which takes place at LSE from 23-25 September organised by the International Growth Centre.
