Abstract
Lithium values are recovered from lithium-bearing micas and amblygonite, but not spodumene, by treating the particulate ore with sulphur trioxide at at least 600 DEG C. to form lithium sulphate which is water-extracted. The sulphur trioxide may be catalytically formed during or prior to the reaction by passing a mixture of sulphur dioxide and oxygen either over a platinum on silica gel catalyst at 450 DEG C., or directly into the reaction vessel at at least 600 DEG C. The sulphur trioxide may be carried by any gas which is inert under the reaction conditions. The lithium sulphate solution may then be titrated with barium chloride to yield lithium chloride which is filtered off from the precipitated barium sulphate, evaporated to dryness and then extracted with n-amyl alcohol, pure lithium chloride being obtained by evaporation of the alcohol.
