摘　　要：针对某铜选厂尾矿选别工艺存在的问题,采用浮选—重选—浮选—重选的工艺,对现工艺进行了改造,铋、钨及锡回收率分别提高了21.15%、4.12%、15.07%,钨锡得到较有效的分离,并提高了金、银等贵金属的回收率,获得了显著的经济效益。Aiming at the existing problems of a copper concentrator, flotation- gravity separation - flotation- gravity separation process is applied to upgrade the current process. The recovery of Bi, W, and Sn is raised by 21.15%, 4. 12% and 15.07% respectively. The Sn and W are effective separated and the recovery of Au and Ag is improved as well, which obtains obvious economic benefit.
