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. 12.3.2
