The Highest Standards of Production
Magnesium oxide is obtained from processing seawater (brine), which contains magnesium chloride (MgCl2). In a parallel stage, MgCl2 is fed to the deboronization system to remove the boron element (B2), whereas concentration gets reduced from 100 parts per million to a maximum of 10 parts per million.
The magnesium hydroxide slurry is then transferred to the washing and filtration unit, where salts (especially calcium chloride) and insoluble solids are removed to form a damp filter cake. Following, the cake is directed to the expressor unit, through which 15% of the water gets removed, forming a cake with 65% solids.
Magnesium oxide is then directed to the briquette pressing unit to obtain 15 millimolar of green briquette and transform the magnesium oxide into larger crystals.
The final stage in the process is the production of high-grade dead burned magnesia (DBM) by burning the green briquette in the vertical kiln at temperatures ranging between 1900°C to 2100°C.
