it is designed for smelting fine chromite ores. The convectional smelting process is designed to handle only lumpy ores which are ideal for ferrochromium production as the fine ores tend to form a sintered layer at the top of the charge, preventing gas escape and thus causing operating difficulties (Buchanan, 2001).

Smelting involves more than just melting the metal out of its ore. Most ores are the chemical compound of the metal and other elements, such as oxygen (as an oxide), sulfur (as a sulfide), or carbon and oxygen together (as a carbonate). To extract the metal, workers must make these compounds undergo a chemical reaction.
