DY-P磷捕收剂在北方某磷矿选矿试验研究中的应用

为了提高北方某磷矿的磷资源利用率,利用DY-P磷捕收剂对该磷矿进行了选矿试验研究。结果表明:DY-P磷捕收剂对该磷矿具有广泛的适应性,受温度影响较小。闭路试验可获得磷精矿品位P2O5达38.12%,回收率达89.45%,杂质铁含量为1.07%,不但降低了铁的含量,而且使选矿药剂成本也大大降低。

Application of DY-P Phosphorus Collector in Mineral Processing Technology for Separation a Phosphorus Ore in Northern China

In order to increase utilization rate of the phosphorus resources from a phosphorus ore in Northern China,an experimental study on using DY-P phosphorus reagent as a collector used for separating a phosphorus ore has been carried out.The results obtained by many experiments showed that the DY-P phosphorus collector has widely adaptability,moreover,the influence of pulp temperature on flotation performance is relatively small.In the closed circuit test,a phosphorus concentrate of 38.12% P2O5 was obtained with a recovery of 89.45%,the content of impurity(iron) is 1.07%.After this kind of DY-P phosphorus collector is adopted,the iron content in concentrate is significantly decreased not only,but the cost of flotation reagents is greatly reduced.
