Copper Smelting - an overview ScienceDirect Topics
Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a
Copper extraction - Wikipedia
The roasting process is generally undertaken in combination with reverberatory furnaces. In the roaster, the copper concentrate is partially oxidised to produce "calcine". Sulfur dioxide is liberated. The stoichiometry of the reaction is: CuFeS2 + 3 O2 → 2 FeO + 2 CuS + 2 SO2Roasting generally leaves more sulfur in the calcined product (15% in the case of the roaster at
