COPPER SMELTING Part 1

Description

Shows the conversion of copper ore and concentrates into metallic copper. The operations depicted include crushing and sampling of the ore; mixing with concentrates; roasting to remove some of the sulphur; melting in reverberatory furnaces; conversion into blister copper of copper matte, which forms beneath the slag; removal of sulphur from the blister copper; and casting the resulting metallic copper into slabs, called anodes, which are sent to the refinery for removal of the remaining small amount of impurities.
