| 摘 要： | 运用化学分析、X射线衍射分析、化学物相分析、扫描电镜、光学显微镜等手段对黄沙坪夕卡岩型多金属矿石中锡的工艺矿物学特征特别是其赋存状态进行了研究。结果表明:矿区锡主要含在石榴子石夕卡岩型磁铁矿石和夕卡岩型钼矿石中;钙铁榴石和磁铁矿是锡的主要载体矿物,二者晶胞参数随锡含量增大而增大,锡在二者晶体结构中可能以Sn4+置换八面体中的Fe3+;锡的化学物相以石榴子石和磁铁矿结合锡为主,夕卡岩型钼矿石中以"胶态锡"为主,锡石含量较少,粒度较小,解离困难,不具选矿回收价值。

| Abstract: | The characteristics of tin technological mineralogy of Skarn-type Multi-metallic Ore in Huangshaping were investigated by means of chemical analysis,X-ray diffraction(XRD),chemical phase analysis,scanning electronic microscopy(SEM) and optical microscopy,especially the mode of occurrence of tin.It is demonstrated that tin is mostly contained in garnet skarn-type magnetite ore and skarn-type molybdenum ore.Andradite and magnetite are main carrier minerals,and their cell parameters increased with increasing t... |
