Copper Smelting

Slag formed in the smelting and converting reactions flows to the slag well. Slag cleaning occurs as a result of contact with lower grade matte in passing through zone 1, by the roast reaction of copper sulfide and copper oxides by the reduction of copper oxide by sulfur and ferrous sulfide, and by the reduction of magnetite.
