Commerce Resources Updates on Pilot Plant for Ashram Rare Earths Deposit

Commerce Resources Corp. (TSXV:CCE) announced an update on the flotation pilot plant for its 100-percent-owned Ashram rare earths deposit.

As quoted in the press release:

Initial results from the shakeout/development phase include 79% recovery with a 24% mass pull(2), and 89% recovery with a 31% mass pull, which compares well to the bench scale 3 inch column results completed at Eriez Flotation Division in Pennsylvania, in January 2015 (82% recovery with a 21-25% mass pull). A test run with an 89% recovery and a mass pull of 44% was also achieved, further demonstrating the potential for higher recoveries above the baseline.

These initial results are in line with the base case flowsheet (test sequence of Flotation + HCl pre-leach + WHIMS) for producing a >40% total rare earth oxide mineral concentrate at >70% recovery and 3% mass pull. The higher mass pulls to the flotation concentrate reported during the shakeout phase of the pilot are due to the elevated levels of fluorite relative to carbonate in the feed material. Therefore, the fluorite will be carried through the flotation and HCl pre-leach stages and not removed until the Wet High Intensity Magnetic Separation (WHIMS) stage.
