【Abstract】 Characteristics and hydrometallurgy processes for Baotou mixed-type rare earth concentrate, bastnasite, and ionic adsorption deposit in China were reviewed. The R & D circumstance and new progresses in extraction and separation of RE elements in China were introduced. Moreover, the development trend of RE hydrometallurgy was predicted. The direction and emphasised fields of research and development are also brought forward as: to R & D high efficient green progresses in hydrometallurgy and separation of RE ore, resolve the waste pollution problem of water, slagand gas, reduce the chemical material consumption and improve comprehensive efficiency of resources; to R & D preparation technology for RE compounds with ultra high-purity and special physical property for extending application fields of RE.更多还原
