Rare Earth InvestingHydro-metallurgical leach studies on the mineral concentrates at the Greenland Minerals and Energy Ltd (ASX:GGG) Kvanefjeld Project have now been completed.
Hydro-metallurgical leach studies on the mineral concentrates at the Greenland Minerals and Energy Ltd (OTCQX:GDLNF,ASX:GGG) Kvanefjeld Project have now been completed.
As quoted in the press release:
Key Outcomes:
- Beneficiation through froth flotation has now been well-tested, and reveals industry-leading upgrade ratios from ore to mineral concentrate representing Leach studies on the mineral concentrates demonstrate that the REE-uranium bearing minerals are highly amenable to conventional acid leach/solvent extraction
- Mineral concentrates can be leached under atmospheric conditions to yield extractions of 90-95% for uraniumand heavy REEs
- Favourable leach solution chemistry allows for the generation of both heavy and light rare earth products
- Major advances in beneficiation and atmospheric leaching allow for the development of an enhanced, efficient flowsheet utilising conventional methods with low technical risk
- Developments eliminate the need for whole-of-ore pressure leaching and significantly reduce the scale of leach circuits, leading to a substantial reduction in capital expenditure
- The Company is looking to finalise its preferred flowsheet and development scenario through Q1 2012, before finalising pre-feasibility work on the Kvanefjeld project
