Copper Concentrate an overview ScienceDirect Topics

4.3 Roasting of Copper Concentrate. One of the drawbacks of matte smelting is the production of large quantities of SO 2 that must be disposed of. One way to avoid this is to roast copper concentrate in the presence of lime or limestone, which captures the sulfur as CaS or CaSO 4. The aim is to produce metallic copper as one of the products, while capturing substantially all the sulfur.
