Copper Smelting Process - Furnaces Used, By .

Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90% of the ore used in smelting. The ore is crushed, screened, and washed before being further processed ready to supply the smelting furnace.
