Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. Wikipedia
Did you know: Bauxite is the principal ore of aluminum and crushing it is the first step in producing aluminum, and then purifying it using the Bayer Process
Bauxite ore is the world's primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions.
Aluminium ore is called bauxite. The bauxite is purified to yield a white powder, aluminium oxide, from which aluminium can be extracted. The extraction is done by electrolysis. But first the aluminium oxide must be made molten so that electricity can pass through it
