根据某选矿厂尾矿的矿石性质，探讨采用重-浮-重的原则工艺对尾矿中的微细粒级锡石进行了回收利用试验研究。其中-0．074唧占试样的91．28％，该试样属于微细粒级难回收锡石。通过采用重-浮-重联合工艺最终获得锡精矿含锡品位为54．48％、回收率为24．73％，中度锡精矿品位26．18％、回收率5．91％，低度锡精矿品位2．41％，回收率18．23％。
根據某選礦廠尾礦的礦石性質，探討採用重-浮-重的原則工藝對尾礦中的微細粒級錫石進行瞭迴收利用試驗研究。其中-0．074唧佔試樣的91．28％，該試樣屬于微細粒級難迴收錫石。通過採用重-浮-重聯閤工藝最終穫得錫精礦含錫品位為54．48％、迴收率為24．73％，中度錫精礦品位26．18％、迴收率5．91％，低度錫精礦品位2．41％，迴收率18．23％。

On the basis of study on the ore property of the tailings, the recovery and utilization of micro fine cassiterite （-0.074mm 91.28%） in the tailings was studies by gravity-flotation-gravity flowsheet. The cassiterite was difficult to recover. The results showed that the content of Sn in cassiterite concentrate was 54.48%, and the recovery was 24.73%. The content and recovery of Sn are 26.18% and 5.91% respectively in moderate-grade cassiterite concentrate. In low-grade cassiterite concentrate, the content of Sn was 2.41%, and the recovery was 18.23%.
