The rare earth elements (REE) are a group of 17 chemically similar elements consisting of the lanthanides, Y and Sc. Their unique physical and chemical properties have made them essential in state‐of‐the‐art equipment ( magnets, catalysts, batteries). A potential supply risk of REE, environmental concerns and economic benefits promote research on processing of secondary .

The rare earths were originally thought to be rare in crustal abundance but this is now recognised not to be the case and they have a similar crustal abundance to elements such as nickel, copper, silver, lead and tin. However, mineable concentrations are less common than for most other ores. The main economic minerals exploited for their rare earth content are:
