Process for separating calcium and nitrogen from lithium.
<??>This process is characterised in that alumina is added to molten lithium so as to form aluminium nitride and calcium oxide, which are insoluble, and the said insoluble materials are separated off with heating to recover purified lithium.
<??>It finds its application in the production of lithium of a quality which is particularly suitable for the manufacture of aluminium-lithium alloys and of electrical battery electrodes.
