锡工艺矿物学

在锡石－硫化物矿石和矽卡岩型锡矿石中，锡主要以锡石形式存在。伴生矿物磁铁矿、 铝榴石，角闪石和萤石中常含有一定量的锡，造成矿石中锡的分散。磁铁矿和萤石中的锡以锡石包裹体形式为主，而石榴石和角闪石中的锡以类质同象形式占优势。锡石是工业上惟一利用的锡矿物，它的高密度及由杂质引起的磁学和电学性质的多样性，决定了回收工艺以重选为主，辅以浮选及其它方法。

Tin technological mineralogy

In cassiterite\|sulphide ore and skarns type tin ore, tin occurs mainly in the type of cassiterite. The associated ores like magnetite, succinite, hornblende and fluorite usually contain a certain amount of tin, causing tin dispersion in the ore. Tin in magnetite and fluorite mainly occurs in the form of cassiterite enclosure, while Sn in garnet and hornblende occurs as isomorphic form in preference. Cassiterite is the only industrially usable tin mineral, whose high density and versatile magnetic and electric properties caused by its impurities have decided its recovery technology, that is, gravity separation is taken as dominance, \{subordinated\} by flotation and other methods.
