ABSTRACT OF THE DISCLOSURE Halides of alkali and alkaline earth metals ("metals") are reduced with gallium, indium or thallium ("reducing metals") at temperatures below their boiling points at vapour pressures at which the gaseous monohali- des of the reducing metals are formed. The quantity of the reducing metals is chosen such that it is sufficient both for the reduction of the metal halides and for the simul- taneous solution of the metals formed, e.g.: MgCl2(s)+2Ga(l) = ??(l)+2GaCl(g); 900°K, 0.02 torr. The metal is distilled off from the melt formed and is con- densed; the metal-free reducing metal is recycled for the reduction of the metal halide. The reducing metal is re- covered from the monohalide for reutilization in the halide reduction; this is effected by reduction of its oxide which is formed either by oxidation of the monohalide, or by oxi- dation of the trihalide resulting in the disproportionation of the monohalide in addition to elemental reducing metal. The continuous process design, the loss-free recycling of the reducing metal, the utilisation of the heat of exother- mal processes, and a minimum consumption of electric power permit a high profitability of producing alkali and alkaline earth metals according to the invention.
