Smelting

Smelting is a process in which the base metal is extracted from the ore by applying heat to it. It is one kind of extractive metallurgy. It is used for the extraction of many metals like copper, aluminium, iron, silver, lead and many other base metals from their respective ores. For the decomposition of the ores, smelting uses heat and chemical ...
