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.
