Calcination: Calcination is a heating process to remove the chemically combined water from alumina hydrate. The hydrate is filtered and washed to rinse away impurities and remove moisture. The calcining kiln is brick-lined inside and gas-fired to a temperature of 1,100C. It slowly rotates and is mounted on a tilted foundation which allows the alumina to move slowly through it to cooling
