Rainbow Rare Earths explores rare earth opportunity in South Africa

Rainbow Rare Earths Limited has entered a MoU with a diversified chemicals group based in South Africa to investigate the opportunity of extracting rare earth elements from a nitro phosphate process stream at its phosphoric acid production plant near Johannesburg in South Africa.
The feedstock for the phosphoric acid production plant originates from the same ore originally mined by Foskor that generated the two gypsum stacks at Phalaborwa. Rainbow has already completed preliminary sampling of the processing stream, with initial results indicating a Total Rare Earth Oxide grade of 0.81% total rare earths oxides (TREO), with a circa 27% weighting to high-value neodymium and praseodymium (NdPr), alongside economic levels of terbium and dysprosium, like Phalaborwa.
