Extraction of Tin/ Stannum. Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.87g/cm 3 , density larger than most of gangue. Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.

An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound.
