中文摘要: 以氨水为浸出剂从铜冶炼渣选矿含铜尾渣中浸出铜，考察了尾渣粒度、浸出剂浓度、反应温度和时间、液固比等对铜浸出率的影响。结果表明，在尾渣粒度0.074~0.105 mm、氨水浓度1.1 mol/L、搅拌速度600 r/min、浸出温度(55±2)℃、反应时间120 min、液固比15∶1的最佳条件下，铜浸出率达到75%以上，其它杂质几乎不被浸出。
Abstract:Copper was selectively leached from copper tailings from mineral processing with ammonium hydroxide as leaching agent. The effects of particle size, ammonium hydroxide concentration, stirring speed, leaching temperature and time, and ratio of liquid to solid (L/S) on copper leaching rate were investigated. The results show that copper leaching rate is 75% above with impurities barely leached under the optimum conditions including particle size of 0.074~0.105 mm, ammonium hydroxide concentration of 1.1 mol/L, stirring speed of 600 r/min, leaching temperature of (55±2)℃, leaching time of 120 min and L/S=15∶1.
