摘　　要：研究了贫锰矿与锌精矿同时浸出及以硫磺形式回收硫。通过试验，得到贫锰矿浸出锌精矿的最佳工艺条件为：始酸质量浓度150g／L，温度90～95℃，液固体积质量比7：1，贫锰矿过量1．5倍，硫酸过量1．5倍，浸出时间4h。在此条件下，锰的一次浸出率为85．2％，锌浸出率为83．0％。Simultaneous leaching of Lean manganese ore and zinc sulphide concentrate and recovery of sulfur as sulphur are researched. The results show that best conditions of simultaneous leaching of manganese and zinc is sulfuric acid of 150 g/L, temperature of 90-95 ℃, ratio of liquid to solid of 7 - 1, lean manganese mass to its theory dosage of 1.5 times, and sulfuric acid mass to its theory dosage of 1. 5 times, leaching time of 4 hours. At the conditions, leaching ratio of manganese is of 85.2%, and leaching ratio of zinc is of 83.0%.
