Abstract
A process for extraction of alumina from aluminum containing ores is disclosed. The process involves the following steps: determining the alumina and silica content in the ore; treating the ore with caustic, subjecting the reaction mass to electromagnetic radiation, leaching soluble intermediate product with water to separate insoluble red mud as residue and to obtain a filtrate containing aluminate, silicate and vanadate; separating silicate and other impurities as residue from the filtrate to obtain beneficiated aluminate liquor and extracting alumina from sodium aluminate by a conventional method.
