METHODS OF DECREASING IMMUNE CONTENT IN MAGNESIUM, PURIFIED MAGNESIUM AND PRODUCING METALLIC ZIRCONIUM Russian patent published in 2018 - IPC C22B26/22 C22B9/10 C22B34/14 

FIELD: chemistry.

SUBSTANCE: method of producing magnesium purified from impurities comprises: combining a zirconium-containing material with the molten magnesium with a low content of impurities containing not more than 1.0 wt % of total impurities in a vessel to form a mixture. The mixture is then kept in a molten state for a time sufficient to allow at least a portion of the zirconium-containing material to react with at least a portion of the impurities to form intermetallic compounds. Then magnesium is separated from intermetallic compounds for the production of purified magnesium, which contains more than 1000 ppm of zirconium, and a reduced level of impurities in addition to zirconium compared to magnesium with a low content of impurities. Purified magnesium containing at least 1000 ppm of zirconium, and methods for producing metallic zirconium using a magnesium reducing agent are also disclosed.

EFFECT: possibility of applying the said magnesium as a reducing agent.
