Solvent extraction offers a better option for gallium recovery among many techniques. The liquid-liquid extraction of gallium(III)-copper(II) solution from hydrochloric acid medium using di-2-ethyl-hexylphosphoric acid (D(2)EHPA) in kerosene was studied. The effect of the reagent concentration and other parameters on the extraction of gallium(III)-copper(II) was also studied. The stoichiometry of the extracted species of gallium(III) was determined based on the slope analysis method. The maximum extraction efficiency of gallium was 99.9%. The gallium that contained organic phase could be stripped completely by 1 M HCl.
