  • Chinese magnesia industry must meet new standards or face shutdown

    Friday, 26 May 2017

    All magnesia companies in Yingkou city must comply with new environmental standards by 30 September, as part of Beijing’s drive to reduce pollution. Producers which failed to meet the strict environmental standards will be shut down.

  • Price briefing 12-18 May

    Friday, 19 May 2017

    The ongoing draconian anti-pollution controls in China continue to disrupt production in a number of minerals, which has lifted prices in bauxite and antimony trioxide. Meanwhile, fused magnesia is no longer available in China; producers announced another rare earth price hike; chromite and silicon carbide prices remained stable; and lithium carbonate spot have risen in China again.

  • Life after steel: Is there more for magnesia?

    Monday, 03 April 2017

    The global steel industry may have taken a turn for the better, but refractory magnesia continues to face oversupply. Cameron Perks, IM Correspondent, looks at why the decline of magnesia’s largest end market is failing to deter new entrants to the sector.

  • Chinese magnesia and refractories: The new normal

    Monday, 22 August 2016

    The Chinese economy is entering a transition from a primarily export-orientated economy to a more consumer-driven economy. At the same time, increasing debt, slower growth and excess production capacity are contributing to what has been labelled as the “new normal” for China. Richard Flook and Ian Wilson examine the effect of this on the Chinese magnesia industry and the Chinese refractory industry.

  • India’s refractories industry: Ready to recover?

    Monday, 22 August 2016

    India’s economy and steel sector have been among a select few worldwide to post healthy levels of growth amid stagnant global GDP rates, but Chinese steel dumping and overcapacity have curtailed growth in the country’s refractories industry, Sunder Singh, IM Correspondent, explains.

Market Brief

Magnesia is the term for magnesium oxide (formula: MgO). Magnesia is produced by mining and processing mainly the hard rock mineral, magnesite, which occurs in two main forms: cryptocrystalline and crystalline.

 

Rarely, magnesia may be produced from other hard rock minerals such as dolomite, brucite, huntite, and serpentinite.

 

Another commercially important source of magnesia is from chemical processing of seawater and magnesia-rich brines, which produces what is sometimes referred to as synthetic magnesia.

 

Grades produced include:

·         Crude magnesite

·         Caustic calcined magnesia (CCM)

·         Dead burned magnesia (DBM)

·         Fused magnesia (FM)

·         Magnesium compounds derived from CCM, eg. magnesium hydroxide, magnesium sulphate.

 

The source of the magnesia determines critical chemical and physical characteristics of the derived magnesia, such as MgO purity (ranges low to high, 85%-99% MgO), ratio of CaO:SiO2, bulk density, and magnesia crystal size.

 

Supply

The world’s total resource of magnesite, the main source of magnesia, is about 13bn tonnes. Six countries host 92% of this, in descending order: China (26%), North Korea (23%), Russia (21%), Slovakia (10%), Australia (7%), and Brazil (5%).

 

World magnesia production (derived from the magnesite) is about 8.5m. tpa, and is dominated by China (49%). Other leading producers include Austria, Brazil, Greece, Russia, Slovakia, Spain, and Turkey.

 

World synthetic  magnesia production (derived from seawater, brines) is about 925,000 tpa, from Brazil, Japan, Mexico, the Netherlands, Norway, Republic of Ireland, Russia, South Korea, and the USA.

 

Leading magnesia producers include:

Grecian Magnesite – Greece

Houying Group – China

Kumas-Kuthaya Magnesite Works Corp. – Turkey

Magnesita Refratarios – Brazil

Magnezit Group – Russia

Martin Marietta Magnesia Specialties – USA

Nedmag Industries Mining & Manufacturing – Netherlands

Queensland Magnesia – Australia

SMZ Jelsava – Slovakia

Ube Material Industries – Japan

 

Markets

Each end use requires different specifications of the preferred magnesia form, so there are many different grades of magnesia on the market. Certain magnesite deposits are better suited to produce certain magnesia grades than others.

 

Crude magnesite: agriculture, glass and ceramics.

 

CCM: agriculture; environment; cement; abrasive binder; pulp and paper; fillers; feedstock for DBM, FM, and magnesium compound production.

 

DBM: refractories.

 

FM: refractories; steel coatings; ceramics.
