Tin processing

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.
