Method of hydrochemical benefication of bauxite

A method of hydrochemical beneficiation of high-ferriferous, high- carbonated bauxites by processing of raw bauxite with solution of complexon in the medium of hydroxide under pressure has been developed. Bauxite products are enriched and the liquid phase, containing the extracted from bauxite, iron oxide. Therefore, bauxite is processed by any standard processing method. Processing of liquid phase provides getting of hematite concentrate and mother liquor of complexon. The mother liquor of complexon after regeneration returns to beneficiation of raw materials as the spent liquor. Hematite concentrate is used to produce iron-ore pellets.
