is metallurgical bauxite and the alumina is extracted from the bauxite in a refinery using a wet chemical caustic soda leach process known as the Bayer process The alumina is then converted to aluminium metal via electrolysis in a smelter using the energy intensive Hall Heroult process Bauxite formation Bauxite forms from the breakdown of clays when large amounts of rainfall leach away the
Naturally there is a certain advantage to refining alumina close to the bauxite mining activity since the red mud can be used to back fill the mine However it is important that the quantity of caustic in the mud is minimised and that the disposal area is sealed to prevent leaching of caustic soda into the surrounding soil Filtration in the process red mud In most circumstances
