该厂于1991年10月建成.产品硫酸锰的各项指标均达到外贸出口标准。该厂耗资100万元.年生产规模为1000t。其生产工艺主要由浸出→压滤→净化→压滤一次蒸发→静置→压滤→二次蒸发→离心→干燥等工序组成。该产品含MnSO_4·H_2O98％。硫酸锰厂的建成试产成功,为该矿今后进行Mn—MnO_2同槽电解试验生产创造了条件;为棠甘山高硫锰矿的利
The plant was completed in October 1991. The indicators of manganese sulfate products have reached the export standards. The plant cost 1000000 yuan. The annual production scale is 1000t. The production process is mainly composed of leaching → pressure filtration → purification → pressure filtration once evaporation → standing → pressure filtration → secondary evaporation → centrifugation → drying and other processes. The product contains MnSO_4 · H_2O98%. Manganese sulfate plant built trial production success for the future Mn-MnO_2 electrolytic tank with the electrolytic test production to create the conditions for the Tong Gan Shan high sulfur manganese ore Lee
