Abstract: This article surveys the research progress and development of rare earth extraction technologies from the leach solution of ionic rare earth ore including precipitation, precipitation -floatation, solvent extraction, ion -exchange and solution membrane separation. Ammonium bicarbonate precipitation will be applied as the major technology in a long period of time for its characteristics of non-toxic leach solution and environment friendliness. Solvent extraction enjoys promising prospect for it can directly produce soluble rare -earth salt or rare -earth solution. It can also perform rare earth extraction grouping for preparing rare earth grouping products. So the former unfavorable status of only producing rare earth oxide mix was transformed by increasing the economic benefits and addressing the demands for green chemical rare earth extraction.
