| titleOfInvention | Improvements in the manufacture of magnesium chloride |
| abstract | Magnesium chloride solution is prepared by distributing hydrochloric acid solution rapidly throughout a slurry of calcium carbonate and magnesium hydroxide, as by spraying whilst the slurry is in rapid motion, to cause selective conversion of the magnesium hydroxide whilst the calcium carbonate is un-reacted, and mechanically removing the suspended solids. The slurry is preferably prepared by partially carbonating a slurry of magnesium and calcium hydroxides obtained by slaking dolomite calcined at 1600-1800 DEG F. Preferably, a slight excess of carbon dioxide is used to form magnesium carbonate, a small quantity of the hydroxide slurry being then added to reconvert the magnesium carbonate; some of the water is then advantageously removed and the cake repulped with magnesium chloride from an earlier stage whereby a more concentrated solution is finally obtained. Solid magnesium chloride may be produced by spray drying, and magnesium therefrom by electrolysis. Chlorine evolved may be converted to hydrochloric acid for use in the process. |
