Oct 11 32 The Mining Process at Copper Mountain Mine Finding Something Unexpected in an Abandoned Copper Mine OPEN PIT MINING OF COPPER IN THE AMERICAN SOUTHWEST s MOVIE Copper is a stable metal largely unaffected by water and air although carbon dioxide will react with the surface of pure copper to form greenish copper carbonate Copper is an excellent conductor of electricity second only to silver and electrical motors generators and wiring are its primary use

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of pure copper called cathodes which will ultimately be made into products for everyday useThe most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different processes involved in determining whether an ore body can be profitably mined Introduction Length 30 minutes Watch Chapter 1 “Exploration” and Chapter 2 “Modern Mining” of Ground Rul Discuss the stages involved in the development of a metal mine Emphasize the decision making processes involved in deciding whether to develop a mine

Impurities have to be removed Copper is purified by electrolysis In this process copper is transferred from an impure anode to the cathode of an electrolytic cell The insoluble impurities fall to the bottom The copper produced by this process is pure copper This is Surface mining is what we use to obtain about 90 percent of the non fuel minerals we extract in the US Gigantic mechanized equipment removes the upper layer of soil and rock mine reclamation Mine reclamation is the process where useful landscapes and productive ecosystems are

Copper Mining Info The above flowsheet shows a basic copper mine process from mine to metal There are two distinct types of copper ore the sulfide ore and the oxide ore The sulfide ores are beneficiated in flotation cells while the oxide ores are generally leached First the copper ore from a open pit mine is blasted loaded and Mining digging or blasting to obtain the copper ore from the surrounding rock Crushing mined copper ore is crushed into very small pieces Grinding crushed copper ore is ground into a powder Concentrating by flotation also known as froth flotation or as ore flotation Mining produce ores containing 2 or less of copper
