Alumina from bauxite

Guilin Hongcheng Bauxite Grinding Mill Factory understands that 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.

Guilin Hongcheng Ore Grinding Machine was founded in 1991. It has been more than 30 years of independent research and development and production of ore grinding machine. The grinding machine has won more than 100 technical patents. It can not only grind bauxite, but also grind limestone, calcite, talc, dolomite, quartz stone, bauxite, marble, feldspar, barite, phosphate rock, coal mine, clay, graphite, kaolin, wollastonite, lime, bentonite, etc. Mohs hardness below 7, Various non-flammable and explosive materials with humidity within 6%. The preparation of alumina from bauxite can use Guilin Hongcheng HC ultra-large pendulum Raymond mill, vertical grinding mill and ultra-fine mill. The fineness range is 80-2500 mesh, and the output is as high as hundreds of tons per hour.
