Copper Sulfide

2.1.1 Crystal structure of copper sulfides. Copper sulfide ore, which accounts for 80% of the copper resource, is the major source for the metallic copper [1].The major copper sulfide ores contain chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), covellite (CuS), and chalcocite (Cu 2 S). The concentrates of copper from sulfides ores are generally performed by flotation and then …

Copper Metallurgy

The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.
