Abstract
The rare earth produced from different ores or solutions is a mixed product containing various individual rare earth elements. To separate them to individual elements presents one of the most challenging separation tasks in metal hydrometallurgy. In comparison with the complex and lengthy processes such as fractional precipitation and crystallization, solvent extraction, also called liquid–liquid extraction, offers a more flexible approach that allows for the production of individual rare earth elements at required purities and quantities. Solvent extraction is currently the dominant technology to separate and purify the individual rare earth elements. The basics of solvent extraction in metal hydrometallurgy are discussed in this chapter.
