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.
