TheBayerProcess. TheBayerProcess which is used by about 80 active plants worldwide is the primary method of producing aluminum frombauxite.Bauxiteore is dissolved in sodium hydroxide or lye at a high temperature and pressure. Then the alumina andbauxiteores are separated by washing out the waste (red muds or sands) from the alumina.
