Greenland Minerals and Energy Ltd. (OTCQX:GDLNF,ASX:GGG) provided an update on the latest metallurgical developments regarding beneficiation, and the positive implications for the Kvanefjeld multi-element project.
As quoted in the press release:
Following an extensive laboratory development program GMEL is nearing the end of metallurgical development of a beneficiation process to produce a high-grade mineral concentrate. Beneficiation development was aggressively initiated in September 2010 and has resulted in a well-tested process utilizing commercially established froth flotation.
The flotation process is able to concentrate 82% of the rare earth elements in 8.5% (mass pull) of the original ore mass. This effectively increases the in-ground ore grade from notionally 1.2% REO to 12% REO in concentrate. In addition to concentrating the rare earth elements, uranium is concentrated to a grade of approximately 0.2% U3O8. Financial analysis indicates there is an economic optimum for the project within a mass pull range of 8-10%.
