摘　　要：湖南东安县锰矿属于低品位软锰矿,采用直接还原浸取法制备了硫酸锰。工业试验结果表明,锰的浸取率达95%,产品质量符合国家标准,原料及能源消耗较低。Manganese sulfate was prepared by direct reduction and leaching from low - grade pyrolusite ore in Hu＇nan Dong＇an County Manganese -mine. The industrial experiment results indicated that the leaching rate of manganese was 95% , and the quality of manganese sulfate was in accord with National Standard, and consumes of raw materials and energy were less.

关 键 词：软锰矿 直接还原 浸取 硫酸锰
