  • Extracting a metal from its ore

    Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2

    In Central and South America -- the leading regional supplier of copper ore and concentrates -- Peru is projected to post robust gains in copper mine output. Production of copper ore and concentrates in Chile, which accounted for nearly 30 percent of global output in 2014, will rise at a more modest pace, limited by the country's aging mines.

  • Where Does Metal Ore Come From?

    Sep 29, 2017Most metals that we use come from metal ores found in the earth's crust. Metal ores are made up of different compounds. Bauxite for example contains about 99 percent aluminum and magnetite about 72 percent iron. These metal ore deposits that contain large percentages of a single element are the easiest to extract.

  • Copper: The mineral native Copper information and pictures

    Native Copper was the only source of copper until the turn of the century, when extraction methods were improved. The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content. Copper ranks second as the most-used metal in the world.

    In most cases copper ores contain between 0.6 and 1 per cent of copper. Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper. In the case of platinum the yield is much lower: 1 tonne of ore usually contains between 3 and 6 grams of platinum. Nonetheless it is still worthwhile mining because the platinum price is high.
