123 Primary Copper Smelting

123 Primary Copper Smelting In roasting, charge material of copper concentrate mixed with a siliceous flux often a low-grade copper ore is heated in air to about 650 C 1200 F, eliminating 20 to 50 percent of the sulfur as sulfur dioxide SO2. Portions of impurities such as antimony, arsenic, and lead are driven off, and some iron is converted to iron oxide.In roasting, charge material of copper concentrate mixed with a siliceous flux often a low-grade copper ore is heated in air to about 650 C 1200 F, eliminating 20 to 50 percent of the sulfur as sulfur dioxide SO2.
