| Based on smelting of copper sulphide concentrate at Baiyin smelter, under rich oxygen smelting condition, the ratio of oxygen and material, mettle grade, Fe3O4 content both in matte and slag, oxygen availability, desulphurization rate, in relation with rich oxygen concentration, copper loss in slag, as well as the influence factors, are studied in this paper.Experiment criteria have been obtained for realising rich-oxygen self-heating smelting with Baiyin copper smelting furnace. |
