What is the complimentary alumina from bauxite?

With the large-scale increase in demand for bauxite, high-quality soil ore has become the object of pursuit. So how many tons of bauxite does 1 ton of alumina need to consume in the production of alumina from bauxite? One ton of alumina consumes 1.85 to 2.6 tons of bauxite, that is, 0.38-0.54 tons of alumina can be extracted per ton of bauxite. The production process of alumina from bauxite: the production of alumina from bauxite can be roughly divided into four categories, namely alkaline method, acid method, acid-base combined method and thermal method. But at present, almost all of them used in industrial production belong to alkali method. Among the four alumina production methods, the Bayer process is the most widely used in the alkaline process.

Bauxite, also known as bauxite or bauxite, is mainly composed of alumina, which is hydrated alumina containing impurities and is an earthy mineral. Mainly used for aluminum smelting. Bauxite can be widely used in foundry, aluminum smelting, cement, refractory bricks, castables and other industries after being ground into fine powder.
