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 6.8-7g/cm 3, density larger than most of gangue.Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.
