tin processing - Mining and concentrating | Britannica
There are two methods of refining impure tin. Fire refining is most commonly used and produces tin (up to 99.85 percent) suitable for general commercial use. Electrolytic refining is used on the products of complex ores and to produce a very high grade of tin (up to 99.999 percent). One fire-refining method is called boiling.

Sep 19, 2022The process of taking out minerals from rocks buried under the earth's surface is called mining. Minerals that lie at shallow depths are taken out by removing the surface layer known as open-cast mining. Deep bores called shafts have to be made to reach mineral deposits that lie at great depths and are called shaft mining.
