LKAB Minerals offer a range of virgin alumino-silicate & magnesia refractory minerals, as well as a range of recycled alumina and magnesia based aggregates.
LKAB Minerals offer a portfolio of alumina based recycled refractory materials, sourced and processed in the UK.

LKAB Minerals Chrome Alumina is produced during the manufacture of aluminothermic chromium metal.
LKAB Minerals process and supply a range of refractory grade Bauxites. The majority of global bauxite ore is used in the production of aluminium metals. However, refractory bauxite is the ore calcined at 1600 - 1650°C which produces a dense, high purity, stable aggregate.
Andalusite is an alumino-silicate mineral occurring in metamorphic rocks as elongated rhombic prisms, sometimes of gem quality.
Calcined Kaolin is an aluminosilicate material produced by heating natural kaolin to high temperatures in a kiln. This calcination process ensures consistent chemical and physical properties, making it ideal for refractory applications.
Alumina (also known as Corundum or Aluminium Oxide) is the family name for inorganic compounds with the chemical formula Al2O3. Fused Alumina is made in electric arc furnace by passing a current between vertical carbon electrodes. The heat generated from this procedure melts the alumina feedstock.
Zirconium silicate (naturally occuring beach sand) has a high thermal expansion coefficient.
Mulcoa is a high mullite chamotte produced by calcining low alkali clays for consistant quality and chemistry.
Mullite is the mineralogical name given to the only chemically stable intermediate phase in the SiO2 - Al2O3 system. It is a high alumino-silicate produced by calcining low alkali clays in a rotary kiln.
Olivine is a naturally occurring mineral magnesium iron silicate sourced from Norway with a high melting point and density. Olivines properties vary depending on the levels of its two main components, forsterite (Fo) and fayalite (Fa). Olivine is named after its olive green colour.
Refractory grade Magnesite
Sa Magnesite is a natural ore identified as a magnesium carbonate, occurring as a primary mineral in igneous and sedimentary rocks. The magnesite ore is mined and classified; this material is then purified and calcined to provide the raw material for refractory grade magnesite products.
Sarca Chamotte is a rotary calcined chamotte produced from pelletised clay minerals.
