Bauxite Beneficiation Plant Design

The mineral, Bauxite, is a rich source of alumina for making aluminum. The metal and its alloys have become an integral part of modern, everyday life. Bauxite (and alumina) is also used in refractories, cement, absorbents, steel, abrasives, rubber, plastic, cosmetics, paints, paper, polishes, glass, enamel and ceramics.

Bauxites are essentially aluminum hydroxides and are formed by the decomposition and hydrolysis of aluminum-bearing silicates. World bauxite resources are estimated to be 55 to 75 billion tonnes. Of this, recoverable reserves are estimated to be around 25 billion metric tonnes. The largest recoverable reserves are in Australia followed by Guinea, Brazil, Jamaica, and India.

Bauxite Beneficiation Operation

Since bauxite is a naturally occurring mineral, it has a number of impurities, like iron, silica, Titania, calcium, and small quantities of phosphorous, sulfur, zinc, magnesium and various carbonate and silicate minerals. For further application or production, it needs to be beneficiated to refine the concentrates.

In bauxite beneficiation process, crushing the raw bauxite materials, usually in hammer mills, is an operation practiced worldwide. Depending on the bauxite, and the quality required, the next stages are screening, scrubbing and washing, magnetic separation, and drying and calcining. Magnetic separation to remove iron, however, is normally practiced in a limited way to produce high value, special grade bauxites. SBM optimized bauxite beneficiation plant design, which can achieve maximum capacity by low cost.
