  Industry Profile

  • Magnesite (MgCO3) is a carbonate of magnesium
  • China is the largest producer of Magnesite in the world - 11,000, 000 metric tones India takes 9th place producing 340,000 metric tones
    Tamil Nadu continued to be the leading state with a share of 72% in total output during 2010-11 followed by Uttarakhand 25%. The remaining 3% was contributed by Karnataka
  • Magnesite is marketed generally after calcination; that is, after converting it into lightly calcined or caustic magnesite by heating the mineral to 800 to 1,000 degree C and dead-burnt variety to 1,800 degree C.
    Fused magneisa is produced by the fusion of the high-grade magnesite in Higgin's or electric arc tilt furnaces between 2,500 and 3,000 degreeC
  • The major proportion (about 98%) of magnesite mined is used for conversion in
    calcined form which finds many applications
    In India, about 96% consumption is accounted by refractory industry
    The BIS has prescribed the IS specification (14303-1995, Reaffirmed 2010) for magnesite for use in refractory industry
  • Sea water or lake bitterns is an alternative source to obtain magnesia by chemical reaction. The main raw materials required other than sea water are, dolomite or limestone, fresh water and sulphuric acid. The magnesia content of sea water is about 0.2%, and even by enrichment with dolomite, around 300 kilograms sea water needs to be processed to obtain a kilogram magnesia
  • The world production of magnesite was estimated at 21.8 million tonnes in 2010. China continued to be the leading producer, accounting for about 64% production, followed by Russia (12%) and Turkey (5% )
    India's primary magnesium metal production capacity is estimated at 900 tones/year
  • As per the Foreign Trade Policy (FTP) 2009-2014, as amended and effective from 05.6.2012, exports and imports of all grades and varieties of magnesite under heading no. 2519 are allowed freely
  • Indian refractory industry, where more than 90% magnesite is used, is experiencing range of challenges. Demand for refractories is promising with India's cement and steel industries growth
