Generally, after mining, the rare bauxite goes through a refining process which it converts it to alumina (the main component in aluminium production). After conversion, it is shipped to countries, such as North America and Europe, where it will be converted to aluminium. In some cases, however, the raw bauxite ore is shipped.

Refining 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.
