Cadmium – Uses, Health Effects And Environmental Effects
 
03:45
Learn which are the uses, environmental effects and health effects of cadmium. Cadmium (Cd) is emitted to water, soil, and air by fossil fuel combustion, non-ferrous metal refining and mining, application, and manufacture of phosphate fertilizers, waste disposal and incineration. It is not usually present in the environment as a pure metal, however, it is most often found in lead, zinc, and copper ores. Uses of cadmium Much of the cadmium that enters the physical body by ingestion comes from terrestrial foods. The daily intake of this metal through food varies by geographic region. Adverse health effects of cadmium This toxic metal is of no use to the human body and is toxic even at very low levels. Once absorbed this metal is efficiently retained in the human body, in which it accumulates throughout life. Occupational exposure to cadmium can lead to numerous adverse health effects including cancer. Kidney stones are also common in cadmium-exposed populations, particularly in exposed workers. Chronic cadmium exposure is strongly connected with progressive renal tubular dysfunction. Urinary, it has been used as a biomarker to indicate ongoing and chronic exposure level in general population. The latest studies confirm that this metal is associated with human pancreatic cancer. Moreover, it increases lipid peroxidation and additionally depletes glutathione and some antioxidants. It also promotes the production of inflammatory cytokines. According to some studies in animals, younger animals absorb more Cd than adults. Environmental effects of cadmium This metal strongly adsorbs to organic matter in soils. Once on the ground, it moves very easily through soil layers and is taken up into the food chain by uptake by plants such as root crops, leafy vegetables, cereals, and legumes. A plant-based diet can considerably reduce the amount of this metal taken into the body from food. Some studies suggest that more Cd is absorbed into the physical body if the diet is high in aft and low in protein, calcium, or iron.

Brazil Mining Disaster Severely Pollutes Local Environment
 
01:08
The collapse of an iron ore tailings dam in the southeast Brazilian state of Minas Gerais last Thursday, which left at least 11 people dead and 12 others missing, has caused widespread environmental destruction, threatening the supply of drinking water and endangering wildlife. Over 62 million cubic meters of water and mining waste was leaked from the dam and flooded into farms and villages many miles downstream, causing severe damage to water resources and the local ecology. Officials said as many 3,200,000 people have been left without drinking water and are relying on aid from outside to maintain their daily lives. Authorities said they are still struggling to tally up the total scale of the damage from the disaster. "We are working on the water quality assessment right now, and we will come up with a report for evaluation. This evaluation will be done by the Minas Gerais’scientific research institution and the Brazilian national research institution. People have realized that this water basin cannot recover quickly from the contamination. It will take long a long time," said Coronel Romilson Caldeira, civil defense secretary in Minas Gerais. Brazilian biologists warned that the damage caused by the accident could permanently scar the environment and will greatly affect the local fishery and agriculture industries.

After an 18-month long wait the Supreme Court has partially lifted the mining ban in Goa. But in a bid to curb illegal mining, the apex court has capped the output at 20 million tonnes a year. While the move will brighten the prospects of domestic players like Sesa Sterlite, it will also help India regain its lost share in the export market. A final call will be taken after a court-appointed panel submits its report on the environmental impact in the next six months.

US Mines & Mineral Resources: "United States: A Ten Talent Nation" 1922 American Motion Picture

Reupload of a previously uploaded film with improved video & sound. Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. http://en.wikipedia.org/wiki/Mining Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner. Ores recovered by mining include metals, coal and oil shale, gemstones, limestone, and dimension stone, rock salt and potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stone and metal has been done since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. The nature of mining processes creates a potential negative impact on the environment both during the mining operations and for years after the mine is closed. This impact has led to most of the world's nations adopting regulations to moderate the negative effects of mining operations. Safety has long been a concern as well, and modern practices have improved safety in mines significantly... Mining in the United States became prevalent in the 19th century, and the General Mining Act of 1872 was passed to encourage mining of federal lands. As with the California Gold Rush in the mid 19th century, mining for minerals and precious metals, along with ranching, was a driving factor in the Westward Expansion to the Pacific coast. With the exploration of the West, mining camps were established and "expressed a distinctive spirit, an enduring legacy to the new nation;" Gold Rushers would experience the same problems as the Land Rushers of the transient West that preceded them. Aided by railroads, many traveled West for work opportunities in mining. Western cities such as Denver and Sacramento originated as mining towns. As new areas were explored, it was usually the gold (placer and then load) and then silver that were taken first, with other metals often waiting for railroads or canals. Coarse gold dust and nuggets do not require smelting, is easy to identify and is easily transported. Modern period In the early 20th century, the gold and silver rush to the western United States also stimulated mining for base metals such as copper, lead, and iron as well as coal. Areas in modern Montana, Utah, Arizona, and later Alaska became predominate suppliers of copper to the world, which was increasingly demanding copper for electrical and households goods. Canada's mining industry grew more slowly than the United States due to limitations in transportation, capital, and U.S. competition; Ontario was the major producer of the early 20th century with nickel, copper, and gold. Meanwhile, Australia experienced the Australian gold rushes and by the 1850s was producing 40% of the world's gold, followed by the establishment of large mines such as the Mount Morgan Mine, which ran for nearly a hundred years, Broken Hill ore deposit (one of the largest zinc-lead ore deposits), and iron ore mines at Iron Knob. After declines in production, another boom in mining occurred in the 1960s and in the 21st century Australia remains a major world mineral producer. Into the 21st century, a globalized mining industry of large multinational corporations has arisen. Peak minerals and environmental impacts have also become a concern. Different elements, particularly rare earth minerals, have begun to increase in demand as a result of new technologies...

Dust Generation during Dumper Movement | Iron Ore Mine
 
00:39
This is a short video which I recorded during my visit to an Iron Ore Mine in the Karnataka region of India, showing dust generation due to Dumper movement, a typical scenario of an iron ore mine in India. Dust generation is major environmental problem faced by people working & living near mining areas, suitable suppression methods are required for controlling them. Water sprinkling is a solution to some extent, but dust generation is not arrested completely. Also a lot of fuel and manpower is wasted in operating water tankers for the purpose. Suitable bio-degradable chemicals (mixed with water) options need to be explored to reduce the dependency on water for dust suppression, offering better results.

Goa's Mines Bleed Its Environment Dry
 
03:03
Unmonitored mining has boomed in Goa in recent years and has had dire effects on the environment. The Goa mining industry is thriving, but its impact on nature and the local population is disastrous. 8% of the state surface is already being mined, mostly to extract iron ore that is exported to China. Over 825 mining sites exist throughout the state, and a large number of projects have been given government's clearance. The very large scale and intensive nature of mining exploitation is a serious challenge to Goa's fragile ecosystem. Indeed, 90 % of Goa's mining leases are within notified wildlife sanctuaries and reserve forests. Large areas of fertile agricultural lands have also been diverted for mining. Huge quantities of mining particles are deposited in rivers, contaminating water sources. Devidas Gaonkar, our Community Correspondent in Goa, has been personally affected by the issue. Belonging to a tribal community, he has witnessed how mining exploitation has encroached on natural resources that are so crucial to sustain life in Goa. His village has been flooded recently because of this excessive mining in the area. In his video, Devidas gives us a powerful and articulate description on how mining is impacting the environment. Deforestation due to mining activity is causing soil erosion and siltation, increasing the risk of flooding and impacting ground water, potentially causing water shortage. With his video, Devidas is adding his voice to the chorus of activists who incessantly warn the government against the risk of excessive mining exploitation. Numerous common people like Devidas have also been courageously protesting mining in the streets and blocking vehicles passing through their villages. Devidas wishes his video to similarly raise awareness, with the hope that the government will soon put a halt to large-scale unmonitored mining, which is proving fatal for Goa's vegetation, water and biodiversity.

हीरों की खान की अनूठी दुनिया | Diamond Mining & Diamonds ore Processing

The Amazing World of Diamond Mines हीरों की खान की अनूठी दुनिया | Diamond Mines - The diamonds Miners Mining and processing Diamonds kimberlite ore The journey of a diamond is a long and complex process. Diamonds are formed deep inside the Earth, they are mined and sorted, they are polished and cut, they are delivered to labs for grading and then finally, they are sold to jewelry stores around the world. Diamond can be found anywhere beneath layer 16, but is most common in layers 12-16. Methods for finding the ore generally fall in two categories: either caving or mining. Either way, you'll need an iron pickaxe to mine the diamonds (also any gold, emerald, or redstone you come across). Usually, kimberlite ore can be found in depths of at least 15 meters. When the diamond-rich depth is reached, the raw material extracted from the ground is then transported to a special screening plant for further processing. There's another form of alluvial mining called artisanal mining. Diamonds formed and stored in these "diamond stability zones" are delivered to Earth's surface during deep-source volcanic eruptions. These eruptions tear out pieces of the mantle and carry them rapidly to the surface. Diamonds are made out of carbon — highly organized carbon, that is. Geologists are still guessing how diamonds formed in the Earth from 1 billion to 3 billion years ago, according to a recent study in the journal Nature, but they think the recipe follows something like this: 1. Bury carbon dioxide 100 miles into Earth. Looking at the crystal form is a quick way of differentiating diamond from most of the other minerals that look like diamond. Diamonds are cubic (isometric) form. The most common mineral that looks like a diamond is quartz and it is hexagonal form. Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamond mining is generally less harmful to the environment than other types of mining, such as gold mining, because it does not make use of toxic chemicals. Despite serious environmental risks, effective regulation and proper planning can minimize diamond mining's environmental impact.

Bad River Band of Lake Superior Chippewa on a proposed iron mine in the Penokee Hills
 
09:54
In 2013, Wisconsin state legislators passed a law that exempted the iron mining industry from environmental protections and greatly reduced the ability of citizens to voice their concerns about the impacts of iron mining on the health of their land and water. The Bad River Band of Lake Superior Chippewa Tribal nation is located at the bottom of the Penokee Hills, between a proposed open-pit iron mine and Lake Superior. This is what they had to say to legislators about how an open-pit iron mine would affect their land and water.

CAP MINING AT 5 MILLION TONNES: GOA FOUNDATION
 
03:09
Environmental NGO, Goa Foundation, has petitioned the Supreme Court appointed panel on capping iron ore mining in Goa to fix the upper limit at 5 million tonnes per annum. The six-member panel of experts is in Goa and will do an environment impact assessment (EIA) study to fix the annual iron ore excavation ceiling for Goa. Goa Foundation which made its submissions to the committee at the State secretariat yesterday has also urged a ban on export of the iron ore from Goa. The panel includes ecologist Dr C R Babu, geologist Dr S C Dhiman, mineralogist Prof B K Mishra, forest officer S Parmeshwarappa and the Goa principal secretary Parimal Rai. They will be in Goa until Friday, January 24. The panel held meetings with officials of 10 different state government departments connected to mining on Thursday at which Dr Claude Alvares of Goa Foundation, who is the petitioner in the Supreme Court case which led to the ban on mining was also invited. The panel is expected to return to Goa on January 27, when heads of all the department have been directed to submit all relevent mining data. Meanwhile, managing director of Sesa Sterlite Ltd, P K Mukherjee also met with members of the panel. Mukherjee told the media that the panel has asked his company to make suggestions in writing. He indicated that Sesa will not put a figure for the annual cap but suggest that the panel look at it holistically and take into account all inter-connected issues including the resource reserves, the infrastructure available and the impact on environment, besides the impact on the economy as well as individual and corporate investments made in the sector.

Iron Ore Mega Mine in Canadian Arctic WILL Destroy It! 3 Undisclosed Fuel Spills!
 
12:40
Lakshmi Mittal, Britain's richest man, is pushing to open an opencast iron ore "mega-mine" inside the Arctic Circle that will include a 150-kilometer railway and two new ports that will bring a ship in every 32 hours—up from the current rate of zero to ten ships a year. The Guardian has the story: Documents seen by the Guardian show that Mittal's company, the world's biggest steel-making group, ArcelorMittal, admits the operations will be undertaken in an area inhabited by unique wildlife including polar bear, narwhal and walrus. The company has just spent nearly $600m (£373m) alongside a US private equity firm buying Baffinland Iron Mines, to seize control and develop the Mary river deposits in the Nunavut region of the Canadian Arctic. the environmental impact statement included talk about efforts to prevent contamination from sewage, wastewater and explosive equipment-washing—but also acknowledged the many possible or probable losses, with no apparent plan to address them. And these are only the predicted impacts: "Building sections of the railway into the edge of several lakes will be unavoidable ... some fish habitat will be lost." "Accidental kills of caribou could occur as a result of project activity." And: "small numbers of ringed seal mortalities could occur as a result of icebreaking activity." The potential value of the mine is estimated at $23 billion worth of iron ore, and as The Guardian explains, the project "highlights the huge commercial potential of the far north as global warming makes industrial development in the region easier." In August 2008 the CBC reported that Baffinland acknowledged three fuel spills.[15] Baffinland's vice-president of sustainable development, Derek Chubb, asserted that the three spills were contained within "secondary engineered containment facilities", and that there was no environmental damage. 5,000 litres of aviation fuel leaked from a fuel bladder at the mine's port facilities on Milne Inlet. The other two leaks of 200 litres, occurred near the mine site. Baffinland acknowledged that the leaks had been found months earlier, but had not been made public. http://www.treehugger.com/files/2011/07/uk-billionaire-pushes-arctic-mega-mine-caribou-whale-seal-deaths-expected-habitat-lost.php?campaign=th_rss baffinland iron http://en.wikipedia.org/wiki/Baffinland_Iron_Mine Energy Minerals Group http://www.emgtx.com/contact.html Houston 811 Main Street Suite 4200 Houston TX 77002 713-579-5000 tel 713-579-5010 fax Contact: Jeff Ball 713-579-5008 tel [email protected] Dallas 2000 McKinney Avenue, Suite 1250 Dallas, TX 75201 972-432-1800 tel 972-432-1801 fax FAIR USE NOTICE: These Videos may contain copyrighted (© ) material the use of which has not always been specifically authorized by the copyright owner.

Rare Earth Minerals Turn Villages to Ruins
 
04:09
Follow us on TWITTER: http://twitter.com/cnforbiddennews Like us on FACEBOOK: http://www.facebook.com/chinaforbiddennews Baotou, Inner Mongolia is China's largest rare earth mineral production base. Although it is a precious mineral resource, rare earth imposes great dangers of pollution. Recently, French media reported from Baotou. Entitled "In China, rare earths are killing villages", the report highlighted massive environmental pollution. It revealed the impact of the production of rare earth minerals on local residents, animals and land. The following is our report. French media 'Le Monde' reported from Baotou, stating that by aerial viewpoint, it looks like a large lake, fed by numerous tributaries. On site, it is actually an opaque discharge covering an area of 10 km2. Surrounding the industrial plants producing 17 minerals are reject waste waters loaded with chemicals. There are no fish or algae The Le Monde article introduced that rock from Bayan obo rare earth ore mine, located 120 kilometers away, are sent here for treatment. The concentration of rare earth in the rocks is very low and must be separated and purified by hydrometallurgical processes and acid baths. In the effluent basin are exist all sorts of toxic chemicals and radioactive elements such as thorium. Ingestion of these toxins causes cancer of the pancreas, lung and blood. A pungent odor exudes within radius of 10 miles. Local villagers have been suffering from cancer. Rows of brown houses in the village have been reduced to rubble. Sichuan environmentalist Chen Yunfei indicates that rare earth refining process causes great environmental pollution and destruction. People are unaware of the specific dangers of this project, and the specialists involved in the decision-making. Chen Yunfei: "Some officials only work on the image projects for profit. They relocate once the money has been made. Some officials collude with the business, caring about nothing but profit, leaving the mess for the public." According to local residents, Baotou used to be a vast grassland. In 1958 the state enterprise Baotou Iron and Steel Company began producing rare earth production. By the end of 1980, locals found that the plant was in trouble. Last year, China Environment News reported that Baotou Iron and Steel Group's tailing dam leakage has caused damage to five surrounding villages. It has affected more than 3000 farmers, and ruined more than 3,295 Acres of farmland. Ma Peng, former Director of the Baotou Rare Earth Research Institute, indicated that due to the lack of a barrier below the tailing dam, the mining waste is directly discharging into the Yellow River. The discharge is at a rate of 300m per year. The residents also said that further pollution has been caused by other industries and thermal power plants. These industries followed rare earth production by the Baotou Iron and Steel Company. Local residents have to breathe air saturated with sulfuric acid and coal dust. Coal dust is airbourne around the houses. Cows, horses, chickens and goats are being killed by these poisons. The locals have fled, and Xinguang Sancun village has now decreased from 2000 villagers to 300. Every family is hit with illness. After 20 years of complaints to the local government, the villagers have finally won promises of financial compensation. These have only been partially fulfilled. Miss Hao, a resident of Baotou: "We all know. The government is too dark. No one cares about the people, whether they live or die, not to mention the pollution." For many years, there have been calls for attention for the issue of Baotou tailing dam discharging thorium radiation to Baotou and into the Yellow River. The hazards and pollution caused by the Baotou tailing dam have never been effectively alleviated. Environmentalist Chen Yunfei: "This is an investment that has hurt several generations. It has polluted the whole environment. This high cost investment ought to be condemned. Our future generations are going to suffer for it." China Environment News indicated that Baotou is located in the stratum fracture zone. In the event of a major earthquake or large-scale rainfall, the rupture of the tailing dam will threaten the surrounding five villages, as well as tens of thousands of lives of the Baotou Iron and Steel workers. If the tailings flow into the Yellow River, it will cause serious pollution to the river. 《神韵》2011世界巡演新亮点 http://www.ShenYunPerformingArts.org/
