Trade is better than aid for Africa. They say. In a journey through copper thieves and mine barons in the north of Zambia, Bram Vermeulen investigates the truth behind that slogan. From a distance they look like ants, the hundreds of men digging holes in the rubble slopes of an old copper mine in Zambia. They are looking for copper ore in the walls of the enormous pit, without wearing helmets and without reinforcing the walls of their caves. Life-threatening, of course. But they find enough to live on. Is it legal, Bram asks. They laugh about it. No of course not. But the Chinese buyer does not really ask where they get their ore from. You just have to leave when the guards of the mine come. How different is it in a huge copper mine in full operation. Huge machines drive off and on. Sirens sound regularly, followed by explosions. Here, 300,000 tons of stone are moved every day, and the copper ore from it yields a profit of hundreds of millions of dollars a year. But it is a foreign company that raises that money. And if the productivity gets too low after about twenty years, the investors will move on. From the air it is easy to see how far-reaching it all is. The mine takes big chores out of the country and turns huge plains into a kind of lunar landscape. But other changes are also visible. Houses, schools, a golf course. Prosperity, therefore, emphasizes a mine boss. Seven years ago this was still a dull provincial town, and now look! A little further on the big changes are about to begin. There is a giant copper mine here, and for that an area of no less than four hundred square kilometers is expropriated. The new owners promise economic prosperity. Did not a city like Johannesburg also start out as a simple mine? Naturally, people living in the area can not stay. They have worked the land for generations, but they can not show ownership documents. They have not been asked anything. They do get compensation for their houses, chickens and fruit trees, but not for the ground. "Everything under the ground is state property," says a representative of the mining company, "and that is what the state can rent out to us." Residents who do not want to leave are squatters who violate the law from that moment on. Even though they were born and lived there all their lives. Those former residents are moved to neat new houses outside the area. With toilet, and bigger than the previous house, but without land to grow food. Some of them seem satisfied with that. Most do not. 'In Africa, land has sentimental value. You are no one without land, 'says one of them. "So you're destroying these people. They will not pass on anything to the next generation. " Episode 6. Copper fever For Africa, trade is better than aid, or so they say. On a journey to copper thieves and mine bosses, Bram Vermeulen investigates the truth behind the slogan.

Copper: How Copper is Mined & made | Things made from Copper uses & properties Copper is a chemical element with symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. On strong heating, copper forms into a black solid of copper oxide. Copper usually does not react with most cold, dilute acids. However, it will react with hot, concentrated sulfuric acid and can react with both dilute and concentrated nitric acid. However, it is the most common of the three and therefore the least valued. All US coins are now copper alloys, and gun metals also contain copper. Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires. Copper, element number 29 on the periodic table, is a mineral that has high ductility, malleability, thermal and electrical conductivity and is resistant to corrosion. These unique properties make it an essential mineral in our everyday lives. Copper is below hydrogen in the electrochemical series and thus does not react with acids to liberate hydrogen, unless they are also strong oxidising agents. Thus, copper metal will not react with dilute sulphuric acid or with hydrochloride acid, HCl, but it reacts with nitric acid to form oxides of nitrogen. Properties: Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. Copper is reddish colored and takes a bright metallic luster. It is malleable, ductile, and a good conductor of electricity and heat. The Roman Empire obtained most of its copper from the island of Cyprus, which is where copper's name originated. Today, copper is primarily obtained from the ores cuprite (CuO2), tenorite (CuO), malachite (CuO. Cu(OH)2), chalcocite (Cu2S), covellite (CuS) and bornite (Cu6FeS4). One of the reasons copper is so important is that it can be made into alloys. That means it can be combined with other metals to make new copper alloys, like brass and bronze. These are harder, stronger and more corrosion resistant than pure copper. An important chemical property of copper is the way it reacts with oxygen. In moist air, it combines with water and carbon dioxide. The product of this reaction is called hydrated copper carbonate (Cu2(OH)2CO3). This compound has a beautiful greenish color, called a patina. As a result of its excellent electrical conductivity, copper's most common use is in electrical equipment such as wiring and motors. Because it corrodes slowly, copper is used in roofing, guttering, and as rainspouts on buildings. It is also used in plumbing and in cookware and cooking utensils. Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.

Copper is one of the most used metal by man; it is an essential element for building construction, power generation and transmission, electronic product manufacturing, and the production of industrial machinery and transportation vehicles. There is no evidence that copper even can be absorbed through the skin. But if it were, this could actually lead to copper poisoning, which may actually be more likely than beneficial effects, that is why it is also s vital to the health of all living things (humans, plants, animals, and microorganisms). In humans, copper is essential to the proper functioning of organs and metabolic processes. The human body has complex homeostatic mechanisms which attempt to ensure a constant supply of available copper, while eliminating excess copper whenever this occurs. Unfortunately there is also a downside to the production of copper in many Third World countries where you find a widespread of fraud, negligence and abuse. Global Witness has documented that government officials in many of the world's most impoverished countries turn a blind eye on harsh labor conditions in the artisanal mines, the complete absence of safety precautions and the failure of both the government and companies to take responsibility for the health and safety of tens of thousands of artisanal miners. In many developing countries, such as the Democratic Republic of Congo, Zambia, Republic of the Congo and some other Third and Second World countries minors you will usually find that governments of those countries do not place any value to the safety precautions of their safety precautions,this leads to huge risks of accidents and deaths in the mines and very often nothing gets investigated. Yes, the big influx of foreign firms or multinationals pouring into those countries presents opportunities for the political elite to enrich themselves. leaving their citizens in misery, but it is the mentality that needs to change, it is the paradigm of those societies that need to change; progress comes with a price. In much of the very impoverished countries there is a growing amount of resentment because the vast profits resulting from copper and any other metal flow out of their countries without them seeing any change in their financial situation. That is why natural resources can be a blessing and a curse to a developing country. Governments in those countries do not believe that universal rights are values that their societies can implement, unconsciously they are not interested in adopting any form of human rights.

Welcome to the Investors Trading Academy talking glossary of financial terms and events. Our word of the day is “Copper”. Copper is a metal that has been known all around the world since ancient times. From West Africa to China to Europe to Central and South America, copper has been mined and worked continuously from as far back as 8,700 BC. As one of the few independently occurring metals, copper has been used in a multitude of forms, from prehistoric pendants to modern-day piping and more. As a highly versatile material, copper can conduct electricity and is a necessary trace mineral in all living things. It also possesses the ability to destroy germs on contact. Copper is mined in large open pits, and Chile and the U.S. have extensive reserves that could be exhausted within the next 50 years. The New York Mercantile Exchange is where copper contracts are traded, states that copper is the third most widely used metal in the world. Like every commodity, copper has its own ticker symbol, contract value and margin requirements. To successfully trade a commodity, you must be aware of these key components and understand how to use them to calculate your potential profits and loss. Copper is extracted from open pit mines. The demand for copper in India and China plays a significant role in determining when, not if, copper reserves will be depleted. Current copper calculations suggest that the earth will run out of copper in as little as 61 years. Copper is an integral part of printed circuit boards, lead free solder, microwave ovens, wave guides, integrated circuits, electromagnets, wiring and piping. Copper is an industrial metal essential to urban modernization. While countries such as China and India strive to develop a western lifestyle, the need for copper will likely increase at the expense of a dwindling supplies. As alternatives are found to replace copper's applications, the price of copper will continue to be volatile. By Barry Norman, Investors Trading Academy

At Sweden largest copper mine, Boliden Aitik, it takes 1000 kgs of earth to obtain three kgs of copper. The mine, located near Gällivare inside the Arctic Circle, is only profitable because its processes are highly automated. Mined ore is transported by a conveyor belt seven kilometers long to a processing plant where giant mills grind it into sand from which the copper can be extracted. The entire site process -- including the concentrator plant, conveyor systems and pumping stations -- is controlled by ABB's Extended Automation System 800xA. ABB's scope of supply also included a gas-insulated substation, a harmonics and power factor correction filter system, low-voltage switchgear as well as maintenance and service.

Ancient mining techniques go well back into our history – well back into ourprehistory, in fact. As we progressed through the Stone Age, with more and more sophisticated tools and weapons being designed and developed, so too,our need for more and better raw materials for these implements. Stone and flint led to copper, then bronze, gold, silver, iron… all in the name of progress, war, technology, vanity or greed. In fact, it’s ironic (pun intended) that the substance prized and even mined by our ancient ancestors for some of the earliest stone tools and weapons – flint – was later a hindrance encountered by Classical miners – who were in many cases also Classical minors – in gold mining galleries described by Pliny the Elder in the 1st century AD as “thought to be the hardest thing that exists, except greed for gold, which is the most stubborn of all things.

धरती के अंदर तेल और गैस के भंडारों का पता कैसे लगाया जाता है? How to find oil and gas? Link : https://www.youtube.com/watch?v=IsgYLbhCUaA #gold #Gold_in_India #Gold_mining Some people cover their cars with Gold, some wear clothes made of gold wire, someone designs Gold their mobile , there are many people in the world who use gold in different way. women of India are also addicted to gold ornaments. people had bought gold to hide their money. But do you know how gold is formed inside the earth? What are the ways to find Gold? How Gold prepared? From which places of India does gold come out? Which countries is the largest gold source? How the gold came inside the earth or how? Humans would never have got the chance to be ashamed of gold. Millions of years ago when the earth was being built. Along with these extraordinary conflicts, billions of tons of molten gold and platinum fell into the center of the Earth and became part of its crude. But today the human race has become so clever that he is in search of everything and is in the process of getting it. So something like this Gold come on earth and today its prices are high. How to find Gold in Under Ground ? So this work happens in the same way as the oil and gas deposits in the ground are detected, in which ground penetration radar (GPR) is used to find out what is in the ground. In fact, it records the physical properties of the soil such as density, magnetic properties, registration, on which the graph is prepared and it is estimated that the core analysis is done under the soil, then the core analysis is done. Drilling it under the ground and removing a little debris and analyzing it. It gives accurate information about what is below. Apart from this, hidden property, metal, i.e. gold, silver, copper etc. are detected through VLF technology. For this the waves are sent within the ground. Once after hitting these waves, the VLF receiver creates an electromagnetic field around that object and produces a sequestration by collision the special metal. This kind of survey is carried out by the team of Archaeological Survey of India (ASI) and Geological Survey of India (GSI). There are 7 different ways to find gold. 1) break the rocks by exploding 2) Milling of stones 3) the process of wetting sand 4) process of cyanide 5) Amalgamation 6) Flotation So by this process, you can guess that finding gold is a very difficult task, this is the reason why gold prices are so high in the market. Gold is very solid and it is very difficult to actually make ornaments. Usually gold is found either in the form of alloy with either pale or silver or alone. It is also found in the form of Calvarites, Sylvainite, Petjite and Cranerite ores. And the gold which is extracted from the mine is in the form of ore, which is absolutely pure gold. Which places of India are extracted gold? Most of the production of gold in India is in the state of Karnataka, where gold is extracted from the mines called Kolar, Hutti and Uti. Apart from this, gold is also extracted from Andhra Pradesh and Jharkhand's Hirabuddin and Kendraakocha mines. If we talk about a mine of Jharkhand, then about 4 grams of gold is extracted from a ton of stone and on average, 7 kg of gold is extracted from a mine here every year. The biggest gold mines in the world. In which Kimberley mine is in Africa, after Grasberg mine which is in Papua, Carlin Nevada mine which is in the US, weladero mine which is in Argentina and the writer's quarry is in Papua New Guinea. 5 countries that produce the most gold or produce gold. 1. China which has been ahead in gold production for many years, China produces 426 tons of gold in about a year. But his government has seen a decline of 6 percent in the past year due to the efforts taken to fight pollution and increase environmental awareness. However, due to the excavation of several mines in existing projects, this year's production is expected to begin. 2. Australia Australia produces 295.1 tons of gold in a year. The mineral industry is more than half of Australia's total exports and generates about 8 percent of GDP. 3.
