  • Origin of the Copper Ores at Corocoro, Bolivia SpringerLink

    Abstract. The metallogenetic role played by the Corocoro copper mine (La Paz Department, Bolivia), formerly considered to be the most important producer of copper in Bolivia, has been emphasized by several authors in their detailed studies. This important role explains in part, why the genesis of these cupriferous ores has, in the past, led toCopper Ore Exporters and Suppliers List in Bolivia,Check new suppliers of copper ore in Bolivia.

    Copper is one of the few metals found in its native elemental state. Elemental copper is found associated with copper ores around the globe, including North America, Africa, Asia, Europe, and South America. Copper and copper ores are commonly found in basaltic rocks, with its most common ore being chalcopyrite (CuFeS 2).Copper Ore Mineral and Healing Properties,Most of the copper ores mined in the United States contain only about 1.2 1.6% copper by weight. The average grade of copper ores in the 21st century is below 0.6% Cu, with a proportion of ore minerals being less than 2% of the total volume of the ore rock. Origin Of The Name.

    The principal ores of copper with the approximate percentage of copper found in each is as follows: Cuprite, a copper oxide which contains 89 per cent of copper. This is the ore that is richest in copper, frequently shading to crystals of native copper. Chalcocite, a copper sulphide containing 80 per cent of copper.The copper mineralization in the Corocoro Basin, Bolivia,Two general types of deposits are recognized in the Corocoro basin--deposits in channel-type depressions containing up to a few percent chalcocite, replacing fossil plant remains; deposits in structural highs, which may be either native copper (grades up to 5 or 10 percent) in reddish sandstones or chalcocite (up to 10 or 20 percent) in grayish sandstones.
