摘　　要：研究了钼酸铵硫化沉淀过程中钼的损失情况,考察了温度、时间、pH、硫化铵试剂用量对金属沉淀率及钼损失的影响。试验结果表明,在温度75℃、时间1h、溶液pH=8、试剂用量为理论量条件下,钼酸铵溶液净化过程中,钼损失率可以降至1.5%以下。The molybdenum loss mechanism in sulfide purification process of ammonium molybdate solution was researched. The effects of temperature, time, pH, reagent usage on molybdenum loss has been examined. The results showed that at the conditions of temperature of 75 ℃ ,time of 1 h,solution pH of 8.0,and theory usage of reagent dosage,Mo loss could be reduced below 1.5%.
