sulphide ore of copper concentration process:

12.3 Primary Copper Smelting

(1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining.

Sulfide Ores - an overview ScienceDirect Topics

If sulfide ores containing iron and copper are to be smelted, an understanding of both the iron and the copper systems is needed. Again, as in Figure 2.1.3 for the Cu–S–O system, the calculations are limited to oxidation by industrial oxygen so that the pressure of SO 2 will be about 1 atm., except where oxygen pressure is appreciable near ...
