Copper Mining and Processing: Processing of Copper

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

1996-11-20 · Commercial copper ore deposits today contain from 0.5 to 6 percent copper, or between 100 and 1000 times the crustal average. In contrast, iron and aluminum constitute around 5.8 percent and 8 percent of the earth's crust, respectively, and their commercial deposits need to be only 3 to 10 times as concentrated as the crustal aver-age....

2019-10-16 · Nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel

2019-8-5 · The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts....
