Rare earth resources are easy to produce low concentration rare earth solution or very low concentration rare earth wastewater in the process of development and extraction, which causes problems such as enrichment difficulties, environmental pollution and resource waste. The sources and characteristics of common low concentration rare earth solutions are introduced, and the principles and research progress of enrichment and recovery technologies of low concentration rare earth solutions in recent years are reviewed, including precipitation, solvent extraction, membrane separation and adsorption separation. The advantages and disadvantages of various enrichment and recovery methods are analyzed, future direction for technological development are also outlined.
