北方某低品位磷矿选矿试验

Experimental research on separating a phosphorus ore in North

针对北方某低品位磷矿的性质特点,采用Dy-P新型磷捕收剂以及组合调整剂和抑制剂,在常温下对该磷矿进行了选矿试验,实验室闭路试验可获得磷精矿品位P2O5达36.88%,回收率达92.69%.结果表明:Dy-P新型磷捕收剂对该磷矿具有较好的适应性,受温度影响较小,具有一定的应用前景.

According the properties and characteristic of the low grade phosphorus in the north,we made the test on the ore with adopting the Dy-P new phosphorus collector and unit regulators and depressants on normal temperature.In the closed circuit test phosphorus concentrate of 36.88% P2O5 was obtained with a recovery of 92.69%.The test results showed that Dy-P phosphorus collector had wide adaptability for the phosphorus ore,with little pulp temperature influence.
