- Production Cost Calcined Bauxite
Bauxite is a natural resource, mined in many countries, principally for its use in the production of aluminum. Calcined bauxite used for HFST is categorized as 'non-metallurgical refractory grade' which comes from high-quality bauxite that is calcined, or heat treated, at 2900-3000°F, to produce a dense, high-purity, stable aggregate.
