摘要
本文介绍了用反浮选和双反浮选方法从贫矿和低品位矿选出合格的磷精矿的实验结果。本实验的P_2O_5回收率为78％～84％,P_2O_5％由17.35％～20.5％提高到29.6％～30.5％,符合湿法磷酸工业要求。
This is an experimental report in heneficiating the lean and low—grade rock by means of reverse—flotation.In the experiments,the recovery of P_2 O_5 was 78～84％, the content of P_2 O_5 was raised from 17.35～20.5％ to 29.6～30.5％.Data obtained meet the requirements of wet process phosphoric acid.
