METHOD OF FLUX RECEIVING FOR MELTING AND REFINEMENT OF MAGNESIUM OR ITS ALLOYS Russian patent published in 2010 - IPC C22B9/10 

FIELD: metallurgy.

SUBSTANCE: into warmed tank it is charged solid salt in the form of solid magnesium chloride of grains fineness not less than 100 mm, it is poured molten salt in the form of waste electrolyte, it is implemented heating and isolation of mixture. Mixture heating is implemented with over-heating up tot temperature 700-800°C and then it is successively loaded magnesium oxide and calcium fluoride in the form of spar of grains fineness up to 3 mm. Received molten mixture is blended, extracted from mixer and cooled. Additionally charging of solid magnesium chloride and molten waste electrolyte into tank is implemented at weight relation solid salt of magnesium chloride to molten waste electrolyte equal to 1:1.1. And in the capacity of magnesium oxide there are used sludges of carnallite chlorinator with mass content of magnesium oxide is not less than 30 wt %.

EFFECT: reduction of materials consumption for manufacturing of flux and reduction of discharges of solid wastes into environment.
