So nearly all rocks on the planet have some metal or mineral content. However, the concentration of this metal is too less for it to be valuable. Ores usually have a very high content of the desired mineral, but it still must be separated from other mixed impurities, This method is known as the concentration of ores.

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.
