Research on Rare Earths Extraction from Acid Leaching Solution of Spent Nickel-Metal Hydride Batteries AITranslate
Abstract AITranslate
Investigation was made of selective extraction of rare earths from the acid leaching solution of spent nickel-metal hydride batteries by solvent extraction. A suitable extraction system was established. Study was made of the effects of the factors such as the initial pH value of raw material liquid, extraction temperature, mixing intensity, extraction time, extraction phase ratio on the extraction efficiency, as well as the effects of such factors as the stripping agent composition and concentration, and stripping phase ratio on the stripping efficiency. In addition, the extraction isotherm of rare earths was measured. Based on the research, pilot-plant experiment was conducted. The results show that the extraction rate of rare earths can reach 99.99 % by five-stage countercurrent extraction. Through the precipitation of the mixed stripping solution with oxalic acid,the rare earths with a purity of 98.49% can be obtained and the contents of all the metallic impurities are less than 0.05 %. The chosen extraction organic phase has a good selectivity for rare earths to ensure the separation of rare earths from other elements.
