FIELD: chemistry.
SUBSTANCE: magnesium chloride and worked out melted electrolyte of magnesium and chlorine preparation electrolytic process are loaded to the vessel in magnesium/chlorine mass ratio equal 1:(1-1,2) respectively. The components are mixed, heated up to temperature exceeding the crystallisation temperature of mixture salts at 200-400°C. Obtained synthetic carnallite in the melt form is decanted, the clarified part is separated and supplied to the electrolytic magnesium and chlorine preparation process. The aforementioned vessel is chlorator melting pot or the stationary carnallite furnace.
EFFECT: process simplification, energy consumption and material expenses decrease.
