Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85oc to 1600c) .This removes moisture thereby increasing the alumina content.

Calcined Bauxite Applications. GLM’s RD-88 Calcined Bauxite is a very durable material with high crush resistance. It has several benefits: Extreme hardness and wear resistance. High resistance to weathering, abrasion, and polishing. High durability. Chemically stable when exposed to intense heat and acid or alkaline agents.
Calcined bauxite is the preferred aggregate for use in HFS systems due to its unique ability to resist polishing and abrasion by vehicle tires. Calcined bauxite is expensive, negatively impacts the environment due to mining, production and transporting processes and has come under supply pressures in recent years.
Jun 25, 1980 associated with bauxite are silicates and iron oxide. Bauxite with a low iron content may be used in the chemical industry. Calcined bauxite, prepared by heating bauxite at high temperature is used by the refractories industry and to make intermediate abrasive products. 3. Alumina, is aluminum oxide (A1203) used for the production of
Apr 12, 2021 The raw material such as calcined saprolite aggregates (65%), calcined bauxite (15%) and Castocem 70 (20%) were used for the said tests (Table 1). The calcined bauxite contains high alumina (Al 2 O 3 – 83%), low iron oxide (Fe 2 O 3 – 3.5%) and moderate silica (SiO 2 – 8%). The Castocem 70 cement is characterized by 70% Al 2 O 3 and 26% CaO.
Imports from China declined by 45 percent. Guyana (42 percent), China (35 percent) and Greece (22 percent) were the leading sources of U.S. refractory-grade calcined bauxite imports. Imports of nonrefractory-grade calcined bauxite in 2011 totaled 236 kt (260,000 st), 23 percent less than the quantity imported in 2010.
