| 摘 要： | 截至2004年,柿竹园多金属矿山约有1万多吨的锡未被回收而进入了尾矿库,开展尾矿中锡的赋存状态研究对综合回收利用尾矿,解决矿产资源短缺问题具重要的意义。本文用ICP-MS、XRF、XRD、激光粒度仪、电子探针等实验手段,研究了柿竹园千吨尾矿库中Sn的赋存状态和分布特征。结果发现尾矿中Sn分布较均匀,随深度的变化不大。在较细粒尾矿中Sn主要以独立锡石和石榴子石中类质同象的形式存在,在较粗粒尾矿中主要是以类质同象形式存在。 |

| Abstract: | It was estimated that more than 10 000 tons of tin had been dumped into tailing dams of the Shizhuyuan Polymetallic Deposit till 2004. To comprehensively reclaim tin from tailing and to resolve shortage of tin resource demands well understanding of tin's occurrence in tailing dams. In this study, we investigated occurrence and distribution characteristics of tin in the Shizhuyuan tailing dam, a kiloton level tailing dam, using ICP-MS, XRF, XRD, laser particle size analyzer, and electronic probe analysis. The results indicated that the distribution profile of tin in tailings is relatively unchanged along the depth profile. However, tin mainly occurs as cassiterite or as isomorphism in garnet in fine tailings but only occurs as isomorphism in garnet in coarse tailings. |
