The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.

Much of the equipment in the initial stage has been over-specified; the washing plant has 6Mt/a capacity and the port can handle 12Mt/a. The very high cost of the greenfield project may therefore be offset to some extent by subsequent lower cost brownfield expansion.

bauxite wash plants. The procedure uses a centrifuge, operating at an rpm and duration designed to match the g-forces in the wash plant, to spin sample vials which are then separated by volume prior to analysis. The overflow and underflow of these vials were found to be very similar in size and consistency to that of known wash plants.

(k arst bauxite) mainly in tropical and sub-tropical climate. Bauxite forms by weathering under conditions favorable for the retention of alumina and the leaching of other constituents of the parent rock. Bauxite rock has a specific gravity between 2.6 to 3.5 kg/m3. It is usually, an amorphous or clay like substance which is however, not plastic.

The bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers. Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina
