摘　　要：采用酸化-硫化沉淀工艺处理紫金山金矿吸附贫液,铜回收率为91.43%,氰回收率为92.31%,处理后溶液中总铜的质量浓度为11.14 mg/L,处理药剂成本为1.52元/t(水),经济效益为5.35元/t(水)。该处理工艺药剂成本低,可回收氰化物和有价金属铜,经济效益、环境效益显著,是处理含铜氰化贫液较为理想的方法之一。This paper used acidification-sulphidization process to treat adsorption lean solution in Zijinshan Gold Mine. The recovery rate of copper is 91. 43 %,of cyanide is 92. 31 %,total copper mass concentration in treated solution is 11. 14 mg /L,agent cost is 1. 52 yuan /t（ water）,economic profit is 5. 35 yuan（ water）. The process,which has low agent cost,the ability to recover cyanide and copper,displays remarkable comprehensive benefits in social,economical and environmental aspects,and is one of the ideal processes for the treatment of copper-containing cyanide solution.
