Bauxite | Refractory Grade Mineral

Refractory bauxite is calcined at 1600 – 1650°C, producing a dense, high-purity and stable aggregate.

High alumina content and a very low alkali content

Low impurities (iron oxide and titania specifically)

Non-hazardous

Non-Toxic

Rotary calcined

Stable Mineral

$Refractory Grade Bauxites$

Product information

Refractory grade bauxite has a high alumina content and a very low alkali content with low impurities (iron oxide and titania specifically), ensuring stable temperature strength.

LKAB Minerals offer RASC Bauxite as standard with the following properties:

RASC Bauxite

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.

Other bauxites

LKAB Minerals can source Chinese Bauxite materials upon request. These include:

Rota-87 Bauxite
Rota-85 Bauxite
RK-90 Bauxite

LKAB Minerals processes and supplies Guyanese refractory grade Bauxite. Please reach out to your sales representative for more information.
