Estimating the term…
The invention relates to a method and a device, by means of which particles with a high magnesium content can be obtained from sea water. The particles can be magnesium hydroxide for example as well as other water-insoluble magnesium salts, such as magnesium sulfate, magnesium carbonate, etc., for example. The particles are produced in a precipitation process using a suitable alkali reagent. When the precipitation is carried out using a nozzle construction according to the invention and/or while adding auxiliary reagents, the size of the obtained particles and the yield thereof can be influenced within a specified range. The aqueous suspension obtained from the process can be further processed in order to produce different products, up to metallic magnesium for metallurgy, using existing technical methods.
A method for producing particles with a high magnesium content from sea water, wherein the readily water-soluble magnesium chloride contained in the sea water is converted into a water-insoluble form and precipitated, further wherein this conversion is effected by raising the pH value in the system to a range equal to or above pH 12 and the precipitated particles are fed to a nozzle arrangement in order to achieve an adjustment of the particle size and a homogenisation of the size distribution of the particles obtained.
