What is Bauxite? Bauxite is primarily a metallic mineral though it is also used as an industrial mineral. It is the only ore used for large scale aluminium production. Although aluminium is the most abundant metallic element in the earths crust constituting about 8%, it usually occurs in clays, soil and rocks that cannot be utilized for its extraction.

202025ensp;0183;ensp;Bauxite tailings, also known as bauxite residue, red mud, red sludge, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).
202036ensp;0183;ensp;The IUPAC defines calcination as quot;heating to high temperatures in air or oxygenquot;. However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect hightemperature
