Dec 08, 2020· First and foremost, we have shown the ability to produce a very high-grade >50% rare earth mineral concentrate, which is something many other Canadian REE projects struggle to achieve. The downstream hydrometallurgical process is expected to benefit significantly from this quality of flotation concentrate grade.
Bench-scale flotation (Phase 1a) and hydrometallurgical (Phase 1b) studies led to the successful development of a flowsheet capable of producing a high grade 48.7% total rare earth oxide (TREO) flotation concentrate at 85.7% TREO recovery.
During those tests, 26 tons of bulk sample feed were processed over 178 hours; each run lasted for 12 continuous hours. About 1,200 kilograms of high-grade REEs flotation concentrate was produced. Grades were between 45.4% and 56.7% light rare earth
