Processing a rare earth mineral deposit using gravity and magnetic
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. Gravity pre-concentration steps ...
