MONTREAL, QUEBEC--(Marketwired - April 16, 2013) - Geomega Resources Inc. ("GéoMégA" or the "Company") (TSX VENTURE:GMA) announces it has finalized the process flow sheet to recover rare earths as a concentrate at its Montviel Rare Earths/Niobium deposit located near Lebel-sur-Quévillon, Québec.
- average 83% overall recovery for Neodymium, Europium, Praseodymium and Gadolinium
- average 64% overall recovery for Dysprosium
- average 45% overall recovery for Yttrium
- average 93% overall recovery for Niobium (after rare earths leaching)
Mixed rare earths concentrate process flow sheet
Beneficiation tests optimizing the recovery of both rare earths and niobium are now completed. Hydrometallurgical tests to produce standard grade mixed rare earths concentrate are also completed. Tests to produce a niobium concentrate from liberated pyrochlore in the leaching residue are nearing completion. G Mining Services Inc., SGS Minerals in Lakefield and CANMET in Ottawa have developed the process flow sheet including: flotation, leaching (early high purity rare earths extraction), HCl regeneration and precipitation.
"The final Preliminary Economic Assessment ("PEA") process flow sheet design significantly reduces reagents consumption and handling. Excellent recoveries of economic elements are confirmed. Further improvements in recoveries, reagents reduction and additional economic elements are possible and will be confirmed at the piloting stage." comments Simon Britt, President and CEO of GéoMégA.
Physical Separation of mixed rare earths concentrate
GéoMégA, in collaboration with Montreal's Polytechnique Physical Engineering Department, is developing its proprietary physical separation technology to process mixed rare earths concentrate into individual elements (see news release dated January 21, 2013). The Company acquired 25 kg of standard mixed rare earths concentrate with similar grades distribution to Montviel to facilitate representative data generation for optimisation testing.
About the Montviel Rare Earths/Niobium deposit
The Montviel project benefits from permanent access, public infrastructure and available labour in the immediate area. A PEA by G Mining Services Inc. is expected in the upcoming months. Anticipated project energy will be provided by the Hydro-Québec distribution grid.
