Title of Process/ Know-how/ Product/Design/Equipment

Production of high purity heavy basic magnesium carbonate from bittern

Application/Uses/Problem being addressed

Heavy basic magnesium carbonates are used in pharmaceuticals as an inert vehicle and an adsorbent. Due to its fine texture and high absorbency, it is used in cosmetic manufacturing as a carrier and retainer of perfumes. It is also used in the rubber industry as a reinforcing agent and as an extender for titanium dioxide in paint, lithographing inks and as a precursor for other magnesium-based chemicals.

Salient Technical Features including Competing Features/ Impact
  • Moderate reaction conditions are involved to produce desired density product using sea bittern
  • Product meets benchmark internationally available product specification
  • TRL Level & Scale of Development:
    TRL 9

    Deployed at commercial scale

    Business scope & opportunity (in terms of scale, cost, market etc.):

    Rise in spending on lifestyle attributed to the rise in disposable income is boosting the demand for cosmetics, personal care products further propelling the magnesium carbonate market. Additionally, adoption of magnesium carbonate in various end-use industries like plastic, rubber, automotive, aerospace, and pharmaceuticals is expected to drive the market potentially. It is used as antacid and filler in other tablets. Additionally, it is used as primary raw material for production of magnesium oxide and other derivatives. This chemical is extensively demanded as smoke suppressant, drying agent and as filler material.
