  • Copper Mining and Processing: Processing Copper Ores

    Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% 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,There are two steps in the extraction of copper metal from chalcocite, a copper ore In the first step, copper(I) sulfide and oxygen react to form copper(I) oxide and sulfur dioxide:2 Cu2 S(s)+3 O2(g) rightarrow 2 Cu2 O(s)+2 SO2(g) In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: Cu2 O(s)+ C(s) rightarrow 2 Cu(s)+There are two steps in the extraction of copper metal from
