Grades of bauxite shown in waves on blue background

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.

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 process and supply Guyanese refractory grade Bauxite. Contact your sales representative for further information. 

Bauxite applications

  • Man standing in large refractory kiln

    Bauxite in refractory applications

    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.

  • Bauxite used in high friction surfacing

    Bauxite in 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. Read more about High Friction Surfacing here.

Bauxite standard grades

  • 5-8mm (-8+5mm)
  • 3-5mm (-5+3mm)
  • 1-3mm (-3+1mm)
  • 0-1mm (-1mm)
  • 0-250μm (-60#)
  • 0-150μm (-100#)
  • 0-15μm (-200#)

Other grades are available on request, please contact your representative via the below form for further information.

Bauxite packaging

Our Bauxite materials are available in 25kg paper sacks, 1000kg bulk bags or as bulk as standard.

The typical properties of RASC Bauxite are:

Chemical properties of RASC Bauxite

Al2O3 [%] 89.7
SiO2 [%] 6.4
Fe2O3 [%] 0.7
TiO2 [%] 3.1

Bauxite origin

  • Our RASC Bauxite is sourced from Guyana in South America.

Bauxite toxicology

Bauxites are non-toxic, non-hazardous stable minerals. You can download the Safety Data Sheet in the section on the right hand side for further information.
