METHOD OF MAGNESIUM GRANULE FABRICATION OUT OF MAGNESIUM OR MAGNESIUM ALLOYS PRODUCTION WASTES Russian patent published in 2009 - IPC B22F9/04 C22B26/22 

FIELD: metallurgy.

SUBSTANCE: invention refers to non-ferrous metallurgy, particularly to methods of magnesium and magnesium alloys granule fabrication out of slime or out of casting wastes of magnesium and its alloys production. Wastes in form of metal-salt mixture are extracted out of a capacity wherein they were produced; then the mixture is cooled, crumbled, regrinded and divided by separation into a metallic constituent in form of granules and salt constituent; further the metallic constituent is dispersed into fractions, while salt constituent is caught in cyclones. Regrinding is performed in a dismembrator. After regrinding the mixture of salt and metallic constituents is continuously fed into a separator by air at specific air consumption of 2-8 m³ per ton of crushed material. After separation the salt constituent is used for obtaining fluxes for magnesium and its alloys production.

EFFECT: increased efficiency and upgraded quality of granules.
