Magnesium minerals

Product information

Magnesium Oxide from LKAB Minerals can be used in a large variety of applications.

Rubber compounding – Varying grades of magnesium oxide, hydroxide and carbonate are used in the rubber industry in a variety of ways: anti-scorch additives, fillers and curing aids. Packed in low-melt poly-sachets, in bags or cartons to meet individual customer requirements

Plastics manufacture – Packed for convenient use, magnesium oxide is a filler, acid acceptor and thickener. Magnesium hydroxide is a flame retardant and smoke suppressant filler.

Water treatment – Magnesium oxide and hydroxide powders and “Hydromag G” granular. Magnesium hydroxide neutralise acidic water and effluents and can absorb or precipitate dissolved metal impurities.

Animal feed supplements – provide a source of magnesium in animal feeds, mixes and farm animal supplemental products.

Construction – Magnesium oxide and magnesium chloride are the essential components of Sorel cement. Magnesium oxide is used in fast–setting road patching compounds.

Chemicals industry – Magnesium oxides, hydroxides and carbonates are used as a starting point in the production of other magnesium chemicals and for pH control in chemical reactions.

Boiler additives – Magnesium oxide and hydroxide raise the melting point of ash, making it friable and more easily removed.

Glass manufacture – ingredients in speciality glass, fibreglass and frits.

Ceramics – basic ingredients in speciality semiconductors and technical ceramic products.

Fertilisers – Magnesium is used in fertilisers and horticultural products.

Applications

Magnesium minerals, including magnesium oxide, hydroxide, and carbonate, are widely used across industries due to their chemical versatility and functional properties. Some key applications include:

Rubber & plastics

• Used as anti-scorch additives, fillers, and curing aids in rubber manufacturing.
• Acts as a flame retardant, acid acceptor, and thickener in plastic production.

Water treatment

• Neutralises acidic water and industrial effluents with magnesium hydroxide.
• Helps remove dissolved metal impurities through absorption and precipitation.

Animal nutrition

• Provides an essential magnesium source in animal feed supplements.
• Supports livestock health by preventing magnesium deficiency in diets.

Construction & cement

• Key component in certain batches of cement and fast-setting road patching compounds.
• Enhances durability and performance in various construction applications.

Industrial & chemical applications
