Processing a rare earth mineral deposit using gravity and magnetic ...
3.2. WHIMS results. The Nechalacho ore was processed using a combination of WHIMS and gravity pre-concentration using either a Knelson (80% - 53 μm feed) or a Falcon (80% - 44 μm feed) Concentrator to exploit the differences in specific gravity and magnetic properties of the different minerals in order to achieve separation.
