The results from the Charley Creek project have confirmed that the rare earth project is amenable to beneficiation from the wet gravity spiral plant.
The Charley Creek process flowsheet represents a low risk and low capital option for early production.
The 1.37wt % of the initial feed recovered 76% Total Rare Earth Oxide (TREO ) at a grade of 6.24% TREO and also a number of opportunities were identified to improve the grade and recovery, particularly of Heavy REO and zircon.
The wet plant concentrate is undergoing conventional electrostatic and magnetic separation (dry plant) to produce a final concentrate product which is expected to contain around 50% TREO.
The wet plant concentrate can be readily transported to a dry plant to produce final concentrate with about 50% TREO.
The dry and wet plants will use the same technology used by mineral sand industry to recover titanium and zirconia minerals.
The Dry Plant test work is expected to be completed by the end of July.
