Extraction Of Copper From Roasted Pyrite Ore

Extraction Of Copper From Roasted Pyrite Ore

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 a silica lined converter. Some silica is also added and a hot air blast is thrown into the mixture to obtain blister copper which is purified by ...
