About aluminium; How it's made; ... Refining process. Alumina is separated from the bauxite by using a hot solution of caustic soda and lime. Pure alumina.
Aluminum is not found freely in nature, requiring the beginnings of aluminum - bauxite ore - to go through a conversion process to produce the metal.
Processing of Bauxite Ores. Bauxite, the primary aluminum ore, uses the Bayer Process to extract alumina from the ore. The processing begins with crushing to 1-2 inch particles and wet screening, to remove some silica fines, which are generally present with bauxite.
Quick Read. Bauxite ore is the world's primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide).
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.
