Extraction of copper from copper slag
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 cas… WebThe copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. …
