Tin processing | Extraction, Refining & Uses | 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

Tin Ore Mining Process

The tin ore has a higher density than symbiotic minerals, so the mining process of tin ore is usually gravity separation.However, tin ore is often accompanied by iron oxide minerals such as magnetite and hematite, so it is impossible to completely separate the ore only by the gravity separation method.
