Geomega Resources Inc.: Breakthrough in Physical Separation of REE
January 15, 2014 (Source: Marketwired) — Geomega Resources Inc. (“GéoMégA” or the “Company“) (TSX VENTURE:GMA), in cooperation with FFE Service GmbH (Munich, Germany), is pleased to announce the successful conclusion of tests confirming physical separation of rare earth elements (“REE“). Based on free flow electrophoresis1 technology, GéoMégA’s physical separation process has the potential to dramatically reduce the capital required to build separation facilities compared to conventional techniques (i.e. fractional precipitation, ion exchange and solvent extraction), optimize REE recovery and improve the environmental performance of operations.
Following months of process optimization, a series of three (3) tests have been conducted with the following characteristics:
- Selected REE in synthetic mixture are europium (Eu), ytterbium (Yb) and lanthanum (La);
- Total REE concentration is approximately 1 g/L (65 millimolar);
- Single pass separation using the prototype instrument of FFE Service GmbH (96 separation channels).
The graphic results (click here) from the three (3) tests highlight the following advantages compared to conventional techniques:
- All REE are separated simultaneously and not sequentially;
- Purity level is 100%.
The process uses no organic solvent which should have a very positive impact on the mitigation of environmental risks in addition to reducing operating costs. The next series of separation tests aims to isolate “neighbour” REE such as neodymium (Nd) vs. praseodymium (Pr) and dysprosium (Dy) vs. terbium (Tb). Results will be disclosed as they become available.
“Not only the separation occurs simultaneously, the slower and less abundant heavy REE are the easiest to isolate using our physical approach. A lot of process optimization and engineering work ahead of us but the confidence level in commercial scale-up is now very high. The world is funding research and development for a sustainable alternative to solvent extraction dominated by China, this breakthrough developed with our partners over the last two years leads us to believe we are close to succeeding.” comments Simon Britt, President and CEO of GéoMégA.
Added value of REE separation

The selling price of a mixed REE concentrate is evaluated according to the distribution of each REE and the impurities of the composition. As finished products require high purity individual REE, the value of the REE in a mixed concentrate is reduced by a significant percentage, i.e. between 25% and 100%. The reduction is based on the criticality of each REE. Currently, the most critical REE are neodymium (Nd) and dysprosium (Dy) due to increasing demand for powerful permanent magnets.
The ongoing preliminary economic assessment (“PEA“) for the Montviel project has a mixed REE concentrate as base case scenario. Since the separation process is in development and the potential impact very favorable, it will be excluded from the PEA base case scenario. Produced by G Mining Services Inc., the Company expects the completion of the PEA during the Company’s third fiscal quarter of 2014.
NRCC Boucherville research facilities
The tests were performed in Munich, Germany by FFE Service GmbH. The Company conducted all analyses at the National Research Council Canada laboratory in Boucherville, Canada. The analyses were done on every sample using ICP-EOS spectrometer.
Dr. Pouya Hajiani, process engineer, and Dr. Gerhard Weber, CEO of FEE Service GmbH, supervised and approved the technical information of this news release.
1 Electrophoretic mobility
Electrophoresis is the migration of charged species (ions, proteins, particles) in solution in the presence of an electric field. Each ion moves toward the electrode of opposite electrical polarity. For a given set of solution conditions and electric field intensity, the migration velocity depends on a characteristic number called the electrophoretic mobility. The electrophoretic mobility is directly proportional to the charge to size ratio of the ion.
GéoMégA has filed patents in multiple jurisdictions to protect its novel separation process. In exchange for the inventor rights and to encourage the conclusive development of the separation technology, the Company shall grant to Dr. Pouya Hajiani, subject to the approval of the TSX Venture Exchange, 1,000,000 common share purchase warrants (“Warrants“), each entitling its holders to subscribe to one additional common shares at an exercise price of $0.15 expiring July 1st, 2018. The Warrants become exercisable upon demonstration of high purity (>99%) separation, in a pilot plant using the separation technology, of the following lanthanides from the Montviel concentrate: neodymium (Nd), dysprosium (Dy), europium (Eu) and praseodymium (Pr).
