Abstract
It is shown that in principle, it is possible to obtain bischofite of high purity by converting bischofite lyes purified from heavy metals, iron and sulfate ions into an insoluble form (magnesium oxide, basic magnesium salts) using their hydrohydrolysis method, washing water-soluble impurities and synthesizing bischofite from a purified thermohydrolysis product and salt acid.
