The extraction performance of gallium in sulfuric acid solution with new alkyl hydroxamic acid DX201 and P204 was studied. The effects of extraction and stripping conditions on gallium extraction performance were investigated. The extraction and stripping isotherms were drawn. The results show that the single-stage extraction rate of gallium is 97.52% under the conditions of VO/VA=1/1, extraction temperature of 25 ℃ and extraction time of 15 min in sulfate solution with mass concentration of sulfuric acid of 20 g/L sulfate solution and organic phase composition of 10%DX201+15%P204+75%260#solvent oil. Using 2.5 mol/L dilute sulfuric acid solution to strip gallium from supported organic phase, the single stage stripping rate of gallium is 94.21% under the conditions of VO/VA=2/1, stripping temperature of 25 ℃ and stripping time of 2 min. The extraction rate of gallium in 3-stage countercurrent extraction is 99.64%, and the extraction performance is stable.
