Achieving High REE Extraction from Hardrock Ores Using Innovation and Recognition of the Specific Ore Mineralogy

Damian Connelly is presenting his technical paper “Achieving High REE Extraction from Hardrock Ores Using Innovation and Recognition of the Specific Ore Mineralogy” at SME Minexchange 2024 Conference & Expo, Wednesday 28th February at 10.25am, Phoenix Convention Centre.

ABSTRACT: The rare earth industry is currently undergoing an unprecedented resurgence driven by the electric vehicle revolution. Each rare earth orebody is different but invariably consists of several rare earth elements that need to be recovered for the process to be economically viable. This necessitates the use of multi-unit processes and the need to deal with complex chemistries. Thus, the process flowsheet, which can become extremely complex, is project specific. So, it is common to limit production to mixed rare earth carbonate products but still requires numerous testwork to optimise, rendering the development timeframe to take around six years at best.

Paper Presentation 2:

Bacterial Heap Leaching of a Copper Sulphide Ores Now Achieves High Recovery

Damian Connelly is presenting his technical paper “Bacterial Heap Leaching of a Copper Sulphide Ores Now Achieves High Recovery” at SME Minexchange 2024 Conference & Expo, Wednesday 28th February at 2.45pm, Phoenix Convention Centre.

ABSTRACT: Significant advances in bacterial leaching of copper sulfide ores has been achieved and laboratory scale testing method for developing a commercial application has been established. Copper recoveries of up to 80% over 120 days is achievable. The success or otherwise of any project is determined by the ore type, testwork required, interpretation of testwork results, ore preparation prior to stacking, and agglomeration requirements. The critical issues that can make or break an operation include bacterial health maintenance, heap temperature control, adequacy of drainage, pad porosity and saturation, and pipe work and irrigation rates. These will be discussed in this paper.
