选矿厂回水对选矿指标影响的试验研究

Research on the Effect of Backwater on the Targets of Mineral Processing Plant

江西某矿山将尾矿库回水返回选矿厂各工序再利用,为了获得利用不同比例回水对技术指标的影响以及不同回水比例对流程循环的影响, 开展了选矿小型试验研究,试验的结果是不同比例的回水及环保回水的使用,都会降低铜精矿的品位及回收率,同时伴生元素回收率也有所降低。

Jiangxi mine tailings backwater will return the process of ore dressing plant for reuse, in order to obtain the effect of using different proportion of return of technical indicators and different proportion of return process of the cycle, to carry out small beneficiation tests, the results of the test are different proportion of water and environmental water use back, will reduce the grade and recovery the rate of copper concentrate, but also reduced the recovery of associated elements.
