湖北某胶磷矿反浮选试验研究

Study on reverse flotation of phosphate rock mined from Hubei province

采用新型捕收剂B-3对湖北某磷矿进行反浮选研究,结果表明:经过反浮选,原矿中的氧化镁质量分数从10.83%降低到1.30%以下,并得到P2O5>37%,MgO<1.3%,回收率>82%的选矿指标。

New collectors were applied in reverse flotation of phosphate rock mined from Hubei province. The results showed that MgO content was reduced from 10.83 % to below 1.30%, and good flotation indexes with P2O5 〉 37 %, MgO〈 1.3 % and P2O5 recovery 〉82% were obtained.
