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, such as 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 neutralises 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.
• Chemical 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.
