摘要/Abstract

摘要： 西藏某铜铅锌多金属硫化矿所处环境特殊，水源缺乏，对矿山开发形成制约。在详细的条件试验基础上，按铜铅混浮—混浮精矿铜铅分离—混浮尾矿浮锌工艺流程，分别采用清水和回水对该矿矿石进行闭路浮选试验，结果表明：采用回水时，所获铜精矿铜品位和铜回收率分别为26.44%和89.67%，铅精矿铅品位和铅回收率分别为62.13%和84.15%，锌精矿锌品位和锌回收率分别为47.03%和73.16%，与采用清水时所获精矿指标差别不大，并且废水回用率可达85%。该结果为解决现场水源缺乏的难题提供了技术依据。

Abstract: A copper-lead-zinc multi-metal sulfide mine in Tibet lives in a complex environment and is lack of water, which restricts the exploitation of mine. Based on the detailed conditioning tests, the closed-circuit flotation tests are made with fresh water and recycling water by the flow-sheet of copper-lead bulk flotation, copper and lead separation of flotation concentrate, and zinc flotation from tailings, The results showed that with the recycled water, copper concentrate with a Cu grade of 26.44% and a recovery of 89.67%, lead concentrate with a lead grade of 62.13% and a recovery of 84.15% and zinc concentrate with a zinc grade of 47.03% and a recovery of 73.16% were obtained respectively. With the fresh water, all technical indexes had no much difference, but the recovery of wastewater reached 85%. This research provides a technical basis for solving the crisis of water resources.
