The density of tin ore is larger than the paragenetic mineral, so the mining process of tin ore apply gravity separation. However, all kinds of Iron oxides exist in those ore, like magnetite, hematite, etc., which cannot be well separated by using gravity or flotation separation.

Mining in Cornwall and Devon, in the southwest of England, began in the early Bronze Age, around 2150 BC, and ended (at least temporarily) with the closure of South Crofty tin mine in Cornwall in 1998. Tin, and later copper, were the most commonly extracted tin mining continued long after the mining of other metals had become unprofitable. ...

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 grams per cubic centimetre, a low melting point of °C ( °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is

The booklet discusses the environmental aspects of metal mining and illustrates the ways science and technology assist in preventing or reducing environmental impacts; Coal Mining and Transportation (Webpage), Energy Information Administration Webpage describing different methods used for mining, processing, and transporting coal.

There are few tincontaining minerals, but only one is of commercial significance and that is cassiterite. The main mining area to be found in the tin belt which goes from China through Thailand, Brima and Malaysia to the islands of Indonesia. Malaysia produces 40% of the world''s tin. Other important tin mining area are Bolivia and Brazil.
