METHOD FOR PRODUCING HIGH PURITY MANGANESE SULPHATE MONOHYDRATE FROM BYPRODUCT OF MANGANESE STEEL ALLOY ELECTRIC FURNACE AND HIGH PURITY MANGANESE SULPHATE MONOHYDRATE PRODUCED THEREBY

摘要

The present invention relates to a method for producing a high purity manganese sulfate monohydrate to obtain the high purity manganese sulfate monohydrate from byproducts generated in a manganese steel alloy electric furnace containing manganese. The method for producing the high purity manganese sulfate monohydrate from byproducts of the manganese steel alloy electric furnace comprises: a step of removing potassium (K) in byproducts generated in the manganese steel alloy electric furnace (S10); a leaching step (S20); a first impurity removing step (S30); a second impurity removing step (S40); a manganese compound recovery step (S50); a step of remelting the manganese compound into manganese sulfate using sulfuric acid (H_2SO_4) (S60); and a step of collecting manganese sulfate monohydrate (MnSO_4·H_2O).
