Copper Smelting - Metallurgist Mineral Processing

2021-1-13  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.

2014-1-1  Slag fuming is a well-established process that has been in industrial operation for more than 80 years. Slag fuming is traditionally used to vaporize zinc from zinc-containing slags, mainly lead blast furnace slag, but also is applied in a few plants for copper-smelting slag. Reduction is achieved by using pulverized coal, lump coal or natural gas.
