摘    要：研究了从湿法炼锌酸浸渣中用硫脲浸出银的工艺及机理.对浸出过程中的各种影响因素如矿浆浓度、浸出剂浓度、反应温度、反应时间、pH值等分别进行了试验研究和分析讨论，给出了最佳工艺条件，在此条件下，银浸出率达89%.

Abstract: This paper describes the process of silver extraction with acid thiourea solution from acidic leaching residues in zinc hydrometallurgy.The factors,which affect the process of leaching,such as pulp density,thiourea concentration,reacting time,and pH,are tested and discussed.The best optional is obtained,and the leaching rate reaches approximately 89%.
