Extraction process of copper

he major steps in the extraction of copper are Copper in Chalcopyrite is reduced to copper sulfide Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag Iron in Chalcopyrite is removed as Iron silicate slag Most of the sulfur in Chalcopyrite turns into Sulphur dioxide SO2
