发布时间：2019-04-17 17:09
【摘要】：氰化渣中含有多种有价金属,但渣中有价金属的回收一直是黄金行业的难题。以山东某黄金企业的氰化渣为研究对象,通过分离浮选试验研究,确定了氰化渣中铜铅浮选回收的最佳工艺流程和药剂制度。最终闭路试验得到了铅品位66.48%、铅回收率89.91%的铅精矿和铜品位15.51%、铜回收率69.09%的铜精矿,实现了该氰化渣中铅铜的分离回收。
[Abstract]:Cyanide slag contains a variety of valuable metals, but the recovery of valuable metals from the slag has been a difficult problem in the gold industry. Taking cyanide slag from a gold enterprise in Shandong province as the research object, the optimum flotation process and reagent system for copper and lead recovery from cyanide slag were determined by separation flotation experiment. The final closed-circuit test obtained the lead grade 66.48%, the lead recovery 89.91% lead concentrate and copper grade 15.51%, copper recovery 69.09% copper concentrate, the separation and recovery of lead and copper from the cyanide slag.
