NioCorp Developments announced that its demonstration-scale processing plant in Quebec inCanada has succeeded in obtaining a rare earth dissolution rate of 86-96% from Elk Creek ore through hydrochloric acid teaching, and has achieved a loading rate of rare earths as hgh as 99% in the follow-on solvent extraction recovery step. These relatively high rates, which were expected, pant to potentially strong rates of overai recovery of separated rare earth oxides, subject to additional demonstratcn testing over the coming weeks.Addrtonal solvent extractxjn steps will be deployed to establish the litimate recovery rates of potential rare earth products. The demonstratcn plant has further established that the rare earths recovered in the initial solvent extraction step are accompanied by oriy two impurities of note: iron and a very small amount of nickel. Given the success of this intial separation step, L3 and NoCorp expect that losses in the additional solvent extraction steps wodd be low.NoCorp is currently focused on demonstrating its ability to recover three high-pwity rare earth products(1) Neodymum-praseodymiim oxide, which is the principal component of neodymiim-iron-boron permanent rare earth magnets. (2) Dysprosium oxide(3) Terbam OxideDy and Tb oxide are critical to the type of powerfd NdFeB magnets used in the traction motors of electric vehicles. However, very little of these high-purity separated rare earth products are made outside of Asia.
