Sarca Chamotte

Refractories & foundries

We offer a range of alumina-silicate & refractory magnesia minerals and a range of alumina and magnesia-based aggregates.

Andalusite - an alumino-silicate mineral

Andalusite

Andalusite is an alumino-silicate mineral occurring in metamorphic rocks as elongated rhombic prisms, sometimes of gem quality.

Aluminium Trihydrate (ATH)

ATH

LKAB Minerals offer a range of fine-ground Aluminium Trihydrate (ATH) products from European manufacturing locations.

Refractory Grade Bauxites

Bauxite

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

Bentonite

Bentonite

Bentonite is used in a wide range of applications within the foundry industry as a binder, as the mineral can withstand high temperatures.

Chrome Alumina

Chrome Alumina

LKAB Minerals Chrome Alumina is produced during the manufacture of aluminothermic chromium metal.

Chromite Sand

Chromite Sand

Natural chrome ore is used as form sand in foundry applications.

Bed materials for bioenergy

Duraheat

Advanced bed materials designed for energy generation efficiency and operational challenges.

Fused Alumina

Fused Alumina

Fused Alumina is made in an electric arc furnace by passing a current between vertical carbon electrodes. The heat generated from this procedure melts the alumina feedstock.

Dead Burnt Magnesite, SKLS Magnesite, and Nedmag Magnesia

Magnesite

Magnesite ore is mined and classified, then purified and calcined to provide the raw material for refractory-grade magnesite products.

Magnesium Oxide

Magnesium

Manufactured Magnesium, providing pharmaceutical grades and technical grade Magnesium for many industries worldwide.

Magnetite

Magnetite

Magnetite is a very pure and milled material, that can be used in various industries.

MinSand - Spherical Refractory Bead

MinSand

MinSand is a perfectly spherical refractory bead produced by fusing and supercooling Bauxite in an electric arc furnace.

Mulcoa

Mulcoa

Mulcoa is a high mullite chamotte produced by calcining low alkali clays for consistent quality and chemistry.

Olivine

Olivine

Olivine is a naturally occurring mineral magnesium iron silicate sourced from Norway with a high melting point and density.

tungsten

Tungsten

It has the highest tensile strength and the lowest thermal expansion of all metals.

zircon

Zircon (Zirconium Silicate)

Zirconium silicate (naturally occurring beach sand) has a high thermal expansion coefficient.

High temperature minerals play a crucial role in the refractories and foundries industry, providing essential properties required for the production of heat-resistant materials and equipment. We offer a wide range of high temperature minerals tailored to fulfil the specific needs of these industries.

One of our key products is magnesite, a natural mineral known for its excellent refractoriness and resistance to high temperatures. It is extensively used in the production of refractory bricks and linings for furnaces, kilns, and other heat-intensive applications. Another important mineral we offer is olivine, which exhibits exceptional thermal stability, making it ideal for use in foundry sands and steel making.

Our high temperature minerals are sourced from carefully selected locations worldwide to ensure consistent quality and performance. We also provide customized grades and sizes to meet the precise requirements of our customers.

In addition to their outstanding heat resistance, our minerals offer other desirable properties such as high chemical stability, low thermal expansion, and good thermal conductivity. These qualities make them reliable and durable in challenging industrial environments.

We are committed to providing high-quality and sustainable solutions for the refractories and foundries industry. With our extensive expertise and reliable supply chain, we offer a range of high temperature minerals that meet the demanding standards of these sectors.
