RAW MATERIALS SALES:

Raw Magnesite

We extract raw magnesite from our own mines.

Caustic Magnesia

We offer caustic magnesia for animal feed, the construction materials industry and special high-grade caustic magnesia for the refractory industry and the chemical industry.

Sintered Magnesia

We have the best magnesite mines in the world. RHI Magnesita produces various grades of sintered magnesia for demanding refractory applications at its plants and for sale to other industrial customers.

Dolomite and Sintered Dolomite

RHI Magnesita produces dolomite and sintered dolomite for the refractory industry.

Magnesia Products

Magnesium-rich raw materials that are processed into products for soil treatment and fertilization as well as for various chemical applications.

Slag Conditioners

Dolomite, magnesite and magnesia products for the treatment of slag in the steel industry.

Magnesium Oxide

Magnesium oxide is a 100% natural product, obtained by controlled calcination of magnesite ore (magnesium carbonate). It shows high chemical purity guaranteed by strict quality control, a high concentration of magnesium, high reactivity, and high residuality on the ground. It is applied in fertilizing, animal nutrition, abrasives and the chemical industry.

Spinels

These are special raw materials for the refractory industry.

Agalmatolite

Agalmatolite mainly consists of two aluminum phyllosilicates: pyrophyllite and muscovite. This mineral is usually applied in the ceramic, refractory, and pulp industries.

Chromite

Chromite is used by the metals industry in the production of iron alloys and stainless steel. In the chemical industry, it is applied as a catalyst, corrosion inhibitor and pigment. For refractories it is used as a basic component in the production of refractory bricks and more recently as sand in casting processes.

Grogs

Grogs are aluminum silicates. They have alumina content among the clays and bauxites content. They are mainly used by the refractory industry.

Commodities

RHI Magnesita offers raw materials such as chrome ore, fused mullite and fused zirconia-mullite as commodities for the refractories industry and for foundries.
