摘要
锡矿物约有六十种，含锡矿物约有二十种。胶态锡是化学物相的概念，是指能溶于１∶３的硫酸中的各类矿物中的锡。它不是某一矿物物相。木锡石、胶状锡石均为锡石的一种，水锡石则是研究得不很清楚的一种矿物。硅酸盐矿物和磁铁矿中都存在类质同象态锡。根据锡矿物和含锡矿物的特性，将矽卡岩锡矿石中的锡分成氧化物相、硫化物相、水锡石相、硅酸锡相四个化学物相，它们各有相对应的矿物，新的化学物相方法利于指导选冶生产。
There
are about sixty kinds of tin minerals,among which nearly twenty kinds of minerals containing tin
(Sn). Colloidal tin,a chemical phase,means the tin of various kinds of minerals which can be
able to dissolve in sulphuric acid (13).Wood tin and colloform cassiterite belong to the series of
cassiterites,but water tin is still unknown to the people.In silicate minerals and magnetites
existed isomorph tin.According to the characteristics of tin minerals and tin-containing minerals,
tin contained in tin minerals of skarn can be divided into oxidephase,sulfidephase,water
tinphase and solicate tinphase,which have correspondent minerals separately.It is concluded
that the new method of chemical phases helps to instruct mineral separation.
