12.3 Primary Copper Smelting

Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into "anodes", and sent to an electrolytic refinery for further impurity elimination. Roasting is performed in copper smelters prior to charging reverberatory furnaces. In roasting,
