ABSTRACT:
Concentrated magnesium chloride solutions are prepared from industrial liquors or brines by evaporating the liquor in a vacuum in two or more stages in a counter current evaporator with crystallization characteristics up to a final concentration of 440 to 475 g/l MgCl.sub.2, a solid content of 12 to 25% by weight and a final temperature of 95.degree. to 105.degree. C, whereafter the liquor is separated from crude crystallized carnallite and sodium chloride, is debrominated by the addition of chlorine, is neutralized by the addition of lime or dolomite milk, is separated in the heat from solid substances, is cooled to effect further crystallization, and is finally separated as a concentrated magnesium chloride solution containing 400 to 465 g/l MgCl.sub.2.
