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 SO2 Roasting generally leaves more sulfur in the calcined product (15% in the case … WebAbstract: This map and table comprise information on 124 world copper smelters (2 of which are closed and 1 of which is under development) and 4 (low-grade solvent …
