FIELD: chemistry.
SUBSTANCE: invention relates to chemistry and can be used to produce commercial-grade bischofite, which is used in construction, processing road surfaces, as well as a source of magnesium. Waste hydrochloric acid reacts with magnesium carbonate in ratio of 0.4-0.6:0.4-0.6, respectively. The reaction takes place at 40-90°C while constantly stirring the reaction mixture.
EFFECT: invention simplifies the process, lowers cost of the product and widens the field of use of the product.
