Abstract
Magnesium oxide is obtained from sea-water or other aqueous liquids containing dissolved magnesium salt by precipitation of magnesium hydroxide with milk of lime, the reaction mixture being subjected to supersonic vibrations. The suspension of reaction products is passed to an adjacent or surrounding decanting vessel and the precipitated solid is withdrawn from the bottom, washed and calcined to magnesium oxide. If desired, the precipitation may be effected in the presence of iron or aluminium salts and the precipitated oxides are thereby mixed with the magnesia. As shown in the <PICT:0821939/III/1> drawings, sea-water is fed to an inner vessel, formed by walls 38, provided with an agitator 3 and a generator 5 for supersonic vibrations. Milk of lime is pumped from tank 14 through lines 17 and 18 and the resulting slurry of magnesia passes over the top of wall 38 into a surrounding annular chamber 8 where the suspension settles. Supernatant water is restored at 13 and the precipitated magnesium hydroxide is withdrawn through line 25 and passed through a chamber 28 where it is subjected to further supersonic vibrations and then to a washing, centrifuging and filtering device 30. The resulting magnesium hydroxide passes through a calcining furnace 32 and a cooler 34 and pulverizer 35.
