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.

Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch. However, some lateritic bauxite ores are readily soluble in caustic, making it

The Bayer process separates alumina from bauxite. Also known as aluminum oxide, alumina then undergoes the Hall-Héroult process, producing pure aluminum. Each step decreases material quantity by half. For example, four units of bauxite will yield two units of alumina. Refining two units of alumina will amount to one unit of pure aluminum.
