Lightly Calcined Magnesite Mgo

Lightly Calcined Magnesite Mgo

Lightly Calcined Magnesite is a highly reactive form of magnesium oxide produced by calcining or calcination crude magnesite at relatively low temperatures (>1300 °C). Applications for lightly /caustic calcined magnesia include water treatment and in production of bonded stones, feed stock, fertilizers and multiple industrial applications. calcined magnesia is available in a wide range of different purities range 80-95% MgO and different particle sizes. We process magnesite in close circuit mill to get best fineness and avoid mixing of foreign particles in the product.


Applications of MgO:

  • Abrasive: MgO is used in abrasive bond stones & grinding stones
  • Agriculture: As magnesium supplement in compound fertilizer
  • Feed additives: An essential nutrient for sheep, goat or cows
  • Construction: In industrial floors, building partition boards and cement
  • Water Treatment: To remove hydrogen sulphide of wastewater
  • Soil Decontamination: To get rid of heavy metals from soil
  • Hydrometallurgy Industry: To precipitate hydroxides of metals from acid leachate solutions of their respective ores
  • MgO can be used as a desulfuriser
