  • Copper Mining and Processing: Processing of Copper Ores

    Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

  • How copper is produced Mining For Zambia

    Step 1. Ore is taken out of the ground. Holes are drilled in the ground (if it’s an open-pit mine) or in the rock-face (if it’s an underground mine), and explosives are placed in them to blast it open.The resulting explosions leave huge quantities of copper-bearing rock also known as ore. Step 2. Ore is broken down into smaller pieces. The large pieces of ore

    2014-06-13· Copper minerals and ore are found throughout the Earth's crust. They occur in both sedimentary and igneous rocks. The outer 10km of the crust contains 33g of copper for every tonne of rock. This is not enough to make it commercially viable to extract the rock. Copper mines are only set up where there is more than 5kg of copper

  • Copper processing Ores Britannica

    Copper processing Copper processing Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

  • Four Big Mines Dominate Zambia's Copper Production

    F our big mines dominate Zambia’s copper production, complemented by several smaller players who also play an important role. All the mines are backed by a wide range of respected international investors. The Zambian government, through its investment-holding company ZCCM-IH, is a minority shareholder in nearly all of them and is, in effect, the biggest shareholder in Zambia
