摘要
对我国某中低品位硅钙质磷块岩进行了双反浮选试验研究,经闭路试验,可以获得P2O5品位30.35%,MgO质量分数0.75%,P2O5回收率83.82%的磷精矿,取得了较好的试验结果。
Double reverse flotation process was tested for a mid-low grade collophane ore that contains silica and calcia in China.After the closed circuit test,the phosphate concentrate that contained 30.35%P2O5,0.75%MgO was obtained with a P2O5 recovery 83.82%,the test result was desirable.
