摘要
对云南某锰银矿的主要化学组成及矿石结构特征进行了研究，选用硫酸亚铁作还原剂对银锰湿法分离进行了实验研究。结果表明：当磨矿细度为-0．074mm粒级占70％～80％，硫酸初始浓度为250g／L，硫酸亚铁加入量为理论值的1．1倍，液固比为5：1，90℃恒温水浴中反应2h时，锰浸出率达89％，银损失率小于1％，可较好分离银与锰。
Based on the studies of chemical compositions and ore texture of manganese-silver ore from Yunnan Province, experiments were carried out on the hydrometallurgical method with ferrous sulfate as reductant, for separating manganese and silver from manganese-silver ore. With a grinding fineness of -0.074 mm 70% - 80%, the initial sulfuric acid concentration of 250 g/L, addition of ferrous sulfate i. i times as much as the theoretical value, liquid/solid ratio at 5 ： 1, the leaching experiment was carried out in a constant temperature water bath at 90℃ for 2 h, resulting in a good separation between silver and manganese, with manganese leaching rate up to 89% and loss rate of silver less than 1%.
