Highlights from the conception of the preliminary processing flow sheet include:
- Mineral concentrate with high total rare earth oxides (« TREO ») and Nb2O5 (« Niobium oxide ») recovery using combined gravity/flotation results in:- Recovery of 87% of TREO (Ce2O3 assays as a proxy) and 95% of Nb2O5;
– 31% whole ore mass reduction.
- Successful use of ferromagnetic separation on whole mineralized ore results in:- Recovery of 97% of TREO (Ce2O3 assays as a proxy) and 96% of Nb2O5;
– 16% whole ore mass reduction.
- Assuming similar success using ferromagnetic separation on mineral concentrate which contained 80% of the iron mineralization present in the mineralized ore, pre-concentrate estimated recovery results in:- Recovery of 85% of TREO (Ce2O3 assays as a proxy) and 90% of Nb2O5;
– 42% whole ore mass reduction.
- Iron by-product separated during physical pre-concentrate preparation.
- Processing flow sheet now conceptually defined for inclusion in the Preliminary Economic Assessment which is currently in progress by G Mining Services Inc.
« The recovery factor in these preliminary results is excellent. Mr. Pearse, GéoMégA’s consulting metallurgist, has added a ferromagnetic separation (step 2) subsequent to gravity/flotation (step 1) which results in additional ore mass reduction and excellent recoveries (97% TREO and 96% Nb2O5), while producing a potential saleable iron by-product. The iron removal triggers further improvements in the pre-concentrate which will reduce hydrometallurgical costs. Additional tests and optimization at every level are ongoing. Aside from location, Montviel has distinct similarities with the world’s largest rare earths resource in Bayan Obo (Inner Mongolia), which is primarily an iron ore deposit. » comments Simon Britt, CEO of GéoMégA.
COREM Laboratory (Québec)
COREM, a consortium of applied research for the processing and transformation of mineral substances, was engaged in March 2012 to undertake parallel testing on ferromagnetic separation on a representative sample of Montviel’s Rare Earths/Niobium enrichment zone mineralization. Approximately 150 kg of uncrushed drill core was delivered to COREM. Testing and results on different grain size, roasting temperatures and gradient strength are expected to be completed in the coming weeks.
About the Montviel Rare Earths/Niobium Project
The Montviel Rare Earths/Niobium/Iron Project is located approximately 45 km west of the Cree First Nation of Waswanipi and 100 km north of Lebel-sur-Quévillon in the southern, developed, part of Quebec’s « Plan Nord » (North of 49th parallel). The Plan Nord is an $80 billion economic, social and environmental development plan of Northern Quebec over a period of 25 years. Montviel’s initial NI 43-101 compliant resource calculation at a base cut-off grade of 1% TREO, released on September 29, 2011, totalled 183.9 Mt averaging 1.45% TREO in the Indicated resources category and 66.7 Mt averaging 1.46% TREO in the Inferred resources category. Montviel, one of the largest TREO resource outside China, has the potential for a significant near term role in the growing permanent magnet sector due to its proximity to infrastructure and available labour.
