when reduced with sodium sulplate, which is benefit for the monomer liberation and obtains better Al-Fe separation effect. The sodium sulplate redox system forms new phases, such as S, Na2S and FeS..., and then providing beneficial way for the gathering of iron grains and gangue minerals. While there is no liquid phase forms in the sodium carbonate redox system, and the migration of iron ions......
