ENCOURAGING RESULTS FROM WET PLANT DEVELOPMENT PROGRAM CHARLEY CREEK RARE EARTH PROJECT
An initial wet plant gravity flowsheet program has been completed on a bulk composite sample of alluvium from Cockroach Dam prospect at Charley Creek. Results confirm the Charley Creek rare earth project is amenable to beneficiation via wet gravity spiral plant. Grade and recoveries from the wet gravity spiral pilot plant were excellent.
The pilot program was conducted at Allied Mineral Laboratories Pty Ltd (AML) in Perth WA under the supervision of Crossland’s metallurgical consultant.
A recovery of 76% TREO (Total Rare Earth Oxide) at a grade of 6.24% TREO contained within 1.37wt % of the initial feed was achieved. A number of opportunities have been identified to improve both grade and recovery, particularly of Heavy REO and zircon. This wet plant concentrate is now undergoing conventional electrostatic and magnetic separation (Dry Plant) to produce a final concentrate product expected to contain approximately 50% TREO.
The proposed Wet and Dry plants for the Charley Creek project would utilise identical technology used by the mineral sand industry for recovery of titanium minerals and zirconia. The Charley Creek process flowsheet represents a low risk and low capital option to enter early production. The Wet Plant concentrate can be readily transported to a Dry Plant, where the final concentrate containing approximately 50% TREO can then be produced for sale or refining to value added products.
Dry Plant test work will be completed by end of July and an update will be provided once results are received.
