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 offer a portfolio of magnesia based recycled refractory materials, sourced and processed in the UK.
LKAB Minerals Chrome Alumina is produced during the manufacture of aluminothermic chromium metal.
Refractory bauxite is calcined at 1600 - 1650°C, producing a dense, high purity and stable aggregate.
Andalusite is an alumino-silicate mineral occurring in metamorphic rocks as elongated rhombic prisms, sometimes of gem quality.
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.
Olivine is a naturally occurring mineral magnesium iron silicate sourced from Norway with a high melting point and density.
Refractory grade Magnesite
Magnesite ore is mined and classified 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.
