Passage
Copper is extracted from copper pyrites. After roasting, the ore is mixed with silica and coke and then smelted in a blast furnace. The matte obtained from the blast furnace is charged into silica lined convertor. Some silica is also added and a hot air blast is blown into the mixture to obtain blister copper which is purified by electro refining.
