Slag In Copper Extraction

During pyrometallurgical copper extraction, smelting is the subsequent operation to the oxidation roasting of the concentrates. In modern pyrometallurgical processes for copper extraction, both operations are facilitated in the same unit, resulting with development of the two main phases silicate slag and the copper matte.
