大兴安岭岔路口钼尾矿分选试验研究

Experimental study on separation of Daxinganling Chalukou Mine's discarded molybdenum tailings

为了解决大兴安岭岔路口钼矿资源利用效率较低的问题,以钼尾矿为研究对象,通过全优先浮选试验和混合浮选试验、单独浮选试验,考察铅锌回收效果。试验结果表明:与其他三种试验效果相比,钼尾矿过滤-强压强拉全优先浮选试验的效果更好,可以得到品位为60. 70%、回收率为0. 02%的铅精矿,同时可以得到品位为37. 44%、回收率为66. 59%的锌精矿。

In order to tackle the problem relating to the low utilization rate of Chalukou Mine′s molybdenum resources,a study is made on the recovery of lead and zinc from the mine′s discarded molybdenum tailings through preferential,mixed and separate flotation tests.Test result shows that in comparison with the above mentioned processes,a best result can be achieved by using the all-preferential flotation process coupled with particle filtering and hydrophilicity/hydrophobicity modification and control processes.With the use of this method,lead and zinc ores with a grade and recovery rate of 60.70%and 0.02%and 37.44%and 66.59%respectively can be obtained.
