【Abstract】 We successfully prepared the MnCl 2-NH 4Cl electrolyte used for electrolytic manganese metal. Using rich-manganous slags as raw material, adding hydrochloric acid in turn and regularly, we could improve the first leaching ratio of manganese(about 80%), and decrease the content of slag.更多还原
