对陕西某磷矿（P2 O5品位为28.53％、MgO质量分数为4.16％）采用一段粗选一段扫选工艺流程进行开路反浮选试验，通过浮选，可获得P2 O5品位为34.12％，w（MgO）为0.074％的合格精矿，且产率为81.03％，P2 O5回收率为96.90％，MgO的排除率为85.00％。
對陝西某燐礦（P2 O5品位為28.53％、MgO質量分數為4.16％）採用一段粗選一段掃選工藝流程進行開路反浮選試驗，通過浮選，可穫得P2 O5品位為34.12％，w（MgO）為0.074％的閤格精礦，且產率為81.03％，P2 O5迴收率為96.90％，MgO的排除率為85.00％。
대협서모린광（P2 O5품위위28.53％、MgO질량분수위4.16％）채용일단조선일단소선공예류정진행개로반부선시험，통과부선，가획득P2 O5품위위34.12％，w（MgO）위0.074％적합격정광，차산솔위81.03％，P2 O5회수솔위96.90％，MgO적배제솔위85.00％。
Open circuit reverse flotation test with one roughing and one scavenging process is done for Shaanxi certain phosphate (P2 O5 grade of 28.53%,MgO content was 4.16%).By flotation,the qualified concentrate with P2 O5 grade of 34.12%,the content of MgO 0.77%,the yield of 81.03%,the recovery rate of P2 O5 of 96.90%,MgO removal rate of 85% can be obtained.
