上井尾矿库尾砂回收利用试验研究

Experimental study of recycling of the tailings of Shangjing tailing pond

阐述了上井尾矿库堆存尾砂回收利用选矿试验研究,确定了该尾砂的选矿工艺流程为单一锌浮选流程,确定磨矿时间及锌浮选的药剂条件。经济指标估算表明,经济效益显著,能够合理利用尾砂资源。

The recycling of the tailings of Shangjing tailing pond in Lanping was experimented, and the single zinc flotation process was determined. In the same time, the grinding time and the reagent condition of zinc floatation were determined. By estimating the economic indicators, this process not only reasonably reused the railings resources, but also obtained remarkable economic benefit.
