Abstract
For separating ferrous, aluminous and manganous contaminations from hydrochloric magnesium chloride solutions the ferrous and aluminous contaminations are precipitated together with optionally present silicic acid and boron compounds at a temperature of 60 to 110 DEG C and a pH-value of 3 to 5.2 by gassing the solution with air and/or oxygen and subsequently the precipitation of manganese is carried out at a pH-value of /4,5, bivalent manganese being oxidised, too. After the precipitation step, the deposit is separated.
