Bauxite residue is a highly alkaline material generated from the production of alumina in which bauxite is dissolved in caustic soda. Approximately 4.4 billion tons of bauxite residues are either stockpiled or landfilled, creating environmental risks either from the generation of dust or migration of filtrates. High alkalinity is the critical factor restricting complete utilization of bauxite ...
Calcined Bauxite – Sibelco
The main constituent of Portalum A25 is Corundum. The material is micronized using Refractory Agglomerated Super Calcined bauxite. Corundum is a crystaline off-colour Aluminium Oxide, characterized by: High inertness in various media. High density and, as a result, low oil absorption. High Mohs hardness of 8.5. High Refractive Index of 1.64.
