    The process requires seawater to be mixed with lightly burnt dolomite in a flocculator causing precipitates of insoluble magnesium hydroxide to settle at the bottom of the tank. This MgOH 2 is pumped out as a slurry and then filtered and converted to magnesium chloride by treating it with Hydrochloric HCl acid and dried. The latter phase of smelting process indicates the final dehydration.

  • Magnesia An Overview Sciencedirect Topics

    Magnesium oxide is converted to magnesium sulfite and sulfate, which are removed from the solution and dried. The mixture of dried magnesium sulfite and magnesium sulfate is regenerated by calcining at about 1,825 F Fink, 1992. The calcining operation produces magnesium oxide, which is returned to the absorption system and a sulfur-dioxide rich gas, which can be fed to a sulfuric acid plant or reduced to
