Red mud 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).
Aluminum processing: Aluminum processing, preparation of the ore for use in various products. In addition to its low density, many of the applications of aluminum and its alloys are based on its high electrical and thermal conductivity, high reflectivity, and resistance to corrosion.
SMHL (a wholly owned subsidiary of Vimetco N.V.) is offering premium grade trihydrate bauxite to the market. The bauxite is gibbsitic type (containing <0.5% MHA) and is used as feed stock for low pressure alumina refineries and for high pressure refineries as a very effective sweetening bauxite.
