Ucore Rare Metals Inc. (TSXV:UCU,OTCQX:UURAF) announced results from bulk scale ore beneficiation testing on material from the Bokan-Dotson Ridge rare earth deposit on Prince of Wales Island, located in Alaska.
As quoted in the press release:
A 20 tonne sample, collected from three locations within the Dotson Ridge deposit, was sent to TOMRA (formerly Commodas Ultrasort) of Wedel, Germany. The sample was processed by a large scale x-ray transmission (XRT) ore sorter. Results show that 52% of the feed was rejected as waste, with 96.3% recovery of rare earth oxides (REO), and a net increase in grade from a 0.77 wt. % REO feed to a 1.56 wt. % output.
Ucore’s President and CEO, Jim McKenzie, said:
The Company is the first in the rare earth industry to demonstrate XRT as a beneficiation technique; a technology already well-established in the tungsten and diamond mining sector. XRT shows the clear potential to dramatically reduce the volume of material feeding the mill facility and an equally dramatic increase in TREO ore grade without a great deal of processing.
