| 摘 要： | 针对锡尾矿锡铁致密共生的特性,以锡尾矿中含的磁性矿物为载体,在强磁场中将锡铁结合体回收并与含钙、镁、硅等的脉石矿物同步分离,经磨矿使锡铁结合体解离,采用磁选回收铁矿物、重选回收锡石的选矿工艺流程,获得铁精矿和锡精矿产品。流程试验试料含锡0.18%、含铁9.74%,获得锡精矿产率1.16%、锡品位4.38%、锡回收率28.23%,铁精矿产率7.04%、铁品位52.62%、铁回收率38.04%的试验指标。

| Abstract: | Based on the characteristic property of tin compacted with iron in tin tailings,magnetic minerals contained in the tailings was take as the carrier,the value substance combined with tin and iron was recycled and separated simultaneously from the gangue containing calcium,magnesium and silicon under the condition of strong magnetic field.The combination of tin and iron was disaggregated by grinding,and then not only iron ore was recycled by magnetic separation but tin stone mineral was recovered by gravity s... |
