针对贵州某中低品位胶磷矿的矿石性质，在磨矿细度-74μm占80%的条件下，以EM-LS-01作为反浮脱镁捕收剂，改性胺类捕收剂EM-FM-01作为反浮脱硅捕收剂，采用双反浮选工艺，最终获得了P2O5品位31.26%，回收率为81.15%，含MgO 0.86%的磷精矿，实现了磷矿物与脉石矿物的有效分离。
針對貴州某中低品位膠燐礦的礦石性質，在磨礦細度-74μm佔80%的條件下，以EM-LS-01作為反浮脫鎂捕收劑，改性胺類捕收劑EM-FM-01作為反浮脫硅捕收劑，採用雙反浮選工藝，最終穫得瞭P2O5品位31.26%，迴收率為81.15%，含MgO 0.86%的燐精礦，實現瞭燐礦物與脈石礦物的有效分離。
