Copper is produced by a looping oxidizing process wherein oxidation of copper sulfide concentrate to molten blister copper by conversion with copper oxides (and optionally oxygen from air) in a one step, molten bath operation to produce molten blister copper, iron oxide slag, and rich SO2 off gas. The blister copper is treated in an anode furnace to reduce the iron content and oxidize residual sulfur, and prepare it for either electrolysis or reoxidation. |
