InactiveCN101845562AMature production processAdvanced and reliable technologyPhotography auxillary processesProcess efficiency improvementL&D processPyrite
The invention discloses an improved device and method for producing electrolytic manganese metal by a two-ore method. The method comprises the following steps of leaching, purifying, deeply purifying and electrolyzing; and two ore raw materials for electrolyzing the manganese metal by the two-ore method are low-grade manganese oxide ores and pyrite ores respectively, wherein the low-grade manganese oxide ores are with the manganese content of 15-25%, and the pyrite ores are tailings (the pyrite ores) of the mineral dressing of non-ferrous metal ores or primary ores. The method has the advantages that a product contains C and S, has low impurity and short production flow, is used for deeply purifying a manganese sulfate solution to eliminate the influence of reductive impurities in the solution on the electrolytic process, thereby realizing the normal electrolytic production and improving the quality of products. The method especially creates ways for the development and the utilization of low-grade lean manganese oxide ores and tailings (the pyrite ores) of the mineral dressing of non-ferrous metal ore.
