The rare earths are hosted in secondary rare earths phosphate minerals that can contain up 60-70% REO. They are finely disseminated within various iron oxides, such as goethite and limonite. The rare earths phosphates within the CLD are predominantly light rare earths enriched, however heavy rare earths mineralisation in the form of crandallite and xenotime does exist in the Duncan Deposit.

Concentration and Separation of Rare Earths from

The separation of pure, individual rare earths from complex ores has presented extractive chemistry with one of its greatest challenges. During the first part of the 20th century, the only technique available for separating rare-earth mixtures was fractional crystallization.

How to Separate Heavy Rare Earth Elements

Twelve pairs of adjacent rare earths were saturated on separate 100-g lots of H form iminodiacetic resin and six pairs of adjacent rare earths were saturated on separate 10-g lots of sulfonic resin. Sulfonic resin loads approximately 10 times as much REE as does iminodiacetic resin; therefore, the different lot sizes for the two resins were selected to keep equivalent total loadings of REE.
