ABSTRACT:
Highly pure (>99.99%) aqueous solutions of gallium chloride are obtained by (i) liquid/liquid extracting an aqueous hydrochloric acid solution of gallium values with an organic phase which comprises a quaternary ammonium chloride extractant, (ii) separating the organic phase from the aqueous phase, (iii) selectively washing said organic phase by intimately contacting same with an aqueous solution of hydrochloric acid to remove any remaining impurities, whereby purified gallium values are transferred from said organic phase into an aqueous solution thereof, and (iv) then separating said organic phase from said resulting aqueous phase, whereby said aqueous phase comprises pure gallium chloride.
