Abstract

A method of producing gallium from gallium-containing dust (e.g. dust which is recovered from gas collecting systems in plants for the electrolytic production of aluminium) comprises leaching the dust in an aqueous hydrochloric acid solution (e.g. at a temperature between 50 DEG and 120 DEG C) whereby gallium is leached as gallium chloride. Gallium chloride is thereafter selectively extracted from the leach solution by an organic phase consisting of substantially undiluted tri-n-butyl-phosphate, whereafter gallium is stripped from the organic phase by water or an alkaline solution e.g. of NaOH with a concentration of 0.1 to 3 M, preferably 1-2 M.
