Refractory grade bauxites have a high Alumina content and a very low alkali content with low impurities (iron oxide and Titania specifically) ensuring stable temperature strength.
Bauxite product uses
Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. In the refractory industry, Bauxite is typically used in ladle working lining, tundish furniture, delta sections, general purpose repair, aluminium melting furnace and mineral processing.
High Friction Surfacing
LKAB Minerals supply a range of Chinese bauxites for use in High Friction Surfacing. Bauxite can be used in pedestrian pathways and road surfacing and can be hot or cold poured onto the road preparation surface. Our Bauxites are BBA and HAPAS type 1 approved.

This consistent high quality grade of bauxite which has a standard density is produced in oil fired rotary kilns.
LKAB Minerals Rota-87 Bauxite is an extremely consistent premium grade bauxite produced using oil fired rotary kilns.
RASC (refractory Aggregate Super Calcined) bauxite is rotary calcined. The bauxite raw material is extremely consistent which LKAB Minerals process into different gradings for use in the refractory industry or as an aggregate in High Friction Surfacing.
LKAB Minerals RG Grey-82 Bauxite is a Chinese calcined bauxite with extremely consistent properties intended for use with hot or cold applied high friction surfacing systems.
