Abstract

Abundant soluble magnesium salts with low impurity were produced as by-product in some industries of Qinghai. These soluble magnesium salts were exploited more easily than some solid minerals, such as magnesites, dolomite minerals, which could accord with the standards of electrolytic process for preparing magnesium materials under rough purification processing. Several different routes on dehydration technology of bischofite (MgCl2ú6H2O) for preparation of anhydrous magnesium chloride (MgCl2) are reviewed in this article, including the partially hydrated magnesium chloride (MgCl2únH2O, n<6). In order to improve the quality of product (MgCl2 or MgCl2únH2O), a few better proposals of improved dehydration technology are proposed. In dehydration process, many factors should be taken into consideration, such as economic benefits, production efficiency, environmental problems, purity.
