Copper Refining - bougainville-copper.eu

Pyrometallurgy. In pyrometallurgy, the concentrate is dried and then heated in a furnace. Chemical reactions that occur during the heating process cause the copper concentrate to segregate into two layers of material: the matte layer, and the slag layer. The bottom, matte layer, contains the copper, and the top, slag layer, contains the impurities.
