METHOD FOR PREPARING CARNALLITE FOR ELECTROLYSIS Russian patent published in 2003 - IPC

Abstract RU 2204627 C1

FIELD: non-ferrous metallurgy, particularly preparation of chlorine and magnesium containing raw material for electrolysis. SUBSTANCE: method comprises steps of adding waste materials after refining and casting of magnesium disintegrated until fraction size no more than 100 micrometers into chlorine-magnesium solutions in order to refine such solutions; adding waste materials in quantity providing relation Ba2+: SO2-4

=(0.9 - 1.0) : 1.0. EFFECT: enhanced quality of carnallite charged into electrolyzer due to removing sulfate-ions from chlorine - magnesium solutions. 3 cl, 1 tbl, 1 ex
