Extraction of Tin/ Stannum-Tin-

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.

Tin processing Britannica

Tin processing, preparation of the ore for use in various products.. Tin (Sn) is a relatively soft and ductile metal with a silvery white colour. It has a density of 7.29 grams per cubic centimetre, a low melting point of 231.88 °C (449.38 °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is allotropic; that is, it takes on more than one form.

About Alluvial Tin Extraction and tin enrichment equipment

Extraction of tin from alluvial tin ore is similar to placer gold enrichment. Generally, gravity separation can help gain great enrichment efficiency with its high recovery rate. For big mineralliberation degree tin ore, easy screening and washing separation can gain high grade tin concentrate. For small mineral liberation degree tin ore, further milling by ball mill or rod mill will be needed
