Abstract

The extraction and separation of rare earth elements is one of the key steps to obtain high-purity single rare earths. The development of new materials and new processes with high-efficiency separation capabilities for rare earth elements is a hot spot for scientific and technological workers worldwide. As a representative new material

ionic liquid has unique physical and chemical properties such as non-volatile

non-flammable

good stability

and adjustable structural properties. In recent years

its application in the field of rare earth element extraction and separation has received extensive attention.This paper provides a systematical review of the publications in recent years reporting the application of ILs in extraction and separation of rare earth (RE) that is essential to obtain high-purity RE products. The ILs-based extraction and separation by use of non-functional and/or functional ILs were here reviewed and discussed in terms of extraction/stripping behaviors

separation performance and mechanisms. The challenges and future directions for the development and application of ILs-based extraction on RE separation were discussed finally.
