Rainbow Rare Earths is advancing its Phalaborwa pilot plant programme in both South Africa and the U.S. The company has initiated the rare earth oxide separation process at its partner K-Technologies, Inc.’s facilities in Lakeland, Florida.

Innovative technology in rare earth separation for Rainbow Rare Earths

The back-end plant in Florida employs continuous ion exchange (CIX) and continuous ion chromatography (CIC) to produce separated rare earth oxides. This technique, pioneered by K-Tech, is an alternative to traditional solvent extraction methods. It will yield critical rare earths used in permanent magnets, including neodymium, praseodymium, dysprosium, and terbium. A video showcasing the CIX / CIC test runs at K-Tech’s facilities is available on the Rainbow website.

Bench scale testwork by K-Tech has shown promising results in rare earth oxide separation. The CIX / CIC pilot plant’s continuous run has started, with the first separated oxides of neodymium and praseodymium expected soon, followed by dysprosium and terbium.
