介绍了混合浮选工艺回收氰渣中铅锌银的生产实践。生产中采用一粗两扫两精的混合浮选流程,选用ATTA药剂作活化剂,丁基黄药与乙硫氮混合使用作捕收剂,获得了铅、锌和银回收率分别为69.25%;86.54%和67.15%,品位分别为17.55%,27.13%和877.26 g/t的混合精矿。 This paper introduces the production practice of recovering lead, zinc and silver in cyanide residue by mixed flotation process. In production, a rough flotation and two-flotation mixed flotation process was adopted. The ATTA agent was used as the activator. Butyl xanthate was used as the collector together with diethylsulfate. The recoveries of lead, zinc and silver were 69.25% ; 86.54% and 67.15% respectively, with the grade of mixed concentrate of 17.55%, 27.13% and 877.26 g / t respectively.
