Bauxite tailings, also known as red mud, red sludge, bauxite residue, 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).
Bauxite is not a mineral, but rather a group of aluminum oxides. The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and Diaspore.Bauxite does not make aesthetic or interesting specimens as far as collectors are concerned, but it holds importance as being the primary ore of ...

Indigenous microorganisms inhabiting bauxite ore deposits and processed wastes such as red muds find application in environmental control. Microbiology and microbial ecology of red mud ponds can be established. The use of acid-producing bacteria to reduce red mud alkalinity has been demonstrated.
Bauxite residue could soon find new life as building material replacing sand and clay-based products thanks to research partnership between UAE's Emirates Global Aluminium and the European research and technology organisation VITO NV. Alongside experts from the University of Leuven in Belgium, the two companies have been conducting research since 2017.
An overview of this conversion process and the materials along the way are described here. Bauxite. Aluminum starts out as bauxite ore – an aluminum ore formed from laterite soil. Bauxite is the world's primary source of aluminum. Before it can become aluminum, however, bauxite destined for use as aluminum must first be processed into alumina.
Use of Bauxite as an Abrasive. Calcined alumina is a synthetic corundum, which is a very hard material (9 on the Mohs Hardness Scale). Calcined alumina is crushed, separated by size, and used as an abrasive. Aluminum oxide sandpaper, polishing powders, and polishing suspensions are made from calcined alumina.
An oxide of aluminum, occurring in nature as various minerals such as bauxite, corundum, etc. It is used as an adsorbent, desiccating agent, and catalyst, and in …
Bauxite 101 Bauxite ore is the world's main source of aluminum. Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds …
Calcium sulfo-aluminate type cements require a higher alumina content that Portland cement and bauxite is frequently used as the alumina source with the result that their raw material cost is markedly higher. The use of bauxite residue offers the opportunity for reducing this cost differential.
Aluminum is the most abundant metal in the earth's crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. Bauxite is the general name given to the hydrated oxides of aluminum.
Coarse Bauxite Residue in Australia. The unique makeup of bauxite derived from Australia's Darling Range presents an added challenge to red mud reuse. The high quartz content of the bauxite results in increased particle size of the waste material derived from alumina production – subsequently referred to as coarse bauxite residue.

Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process.
