补充资料：锡石
| 锡石 cassiterite 锡的氧化物矿物。成分为SnO2。含锡78.6％，是常见的锡矿物，炼锡的最主要矿物原料。常含铁、钽和铌等氧化物的细分散包裹物。四方晶系，晶体常呈四方双锥状，双锥短柱状；膝状双晶常见。集合体大多呈粒块状；外壳呈葡萄状等而内具同心放射纤维构造的称木锡石。纯净者几乎无色 ，一般呈黄棕至棕黑色；条痕白色。金刚光泽，断口呈油脂光泽。莫氏硬度6～7，比重6.8～7.1。主要产于花岗岩分布地区的伟晶岩、气化高温热液矿脉中。因其硬度高、比重大、抗风化力强，常富集成砂矿，称砂锡。中国、马来西亚、印度尼西亚、玻利维亚、泰国等是锡石的主要出产国。中国以广西南丹大厂规模最大；云南个旧锡矿开采历史悠久，有锡都之称。
