Abstract
An electrolytic process is provided for the recovery of lithium values from a molten salt bath containing MgCl.sub.2, CaCl.sub.2, NaCl, KCl and LiCl. The salt composition in the molten state is subjected to the sequential depletion by electrolysis of the elements Mg, Ca, Na, respectively, either in substantially the elemental form or as an alloy thereof under multistage operating conditions to provide a depleted salt composition comprised substantially of the binary LiCl-KCl from which lithium is subsequently recovered by electrolysis as lithium per se or an alloy of Al/Li.
