The Bayer Process is a hydrometallurgical method used to extract alumina (aluminum oxide) from bauxite ore. It involves dissolving the aluminum- bearing minerals in a hot solution of sodium hydroxide, followed by precipitation of aluminum hydroxide, which is then calcined to produce pure alumina.
The principal industrial process of refining bauxite to produce alumina is called
