Defense Metals Updated Beneficiation Results Confirm the Production of a High Grade Flotation Concentrate at High Recovery
Considering all open-circuit flotation tests, at a feed grade of 3% TREO (Total Rare Earth Oxide), the best fit line indicated 80% recovery to a 45% TREO concentrate.
- Considering all open-circuit flotation tests, at a feed grade of 3% TREO (Total Rare Earth Oxide), the best fit line indicated 80% recovery to a 45% TREO concentrate.
- Closed circuit operations, as practised in flotation plants, can be expected to deliver higher recovery and grade.
- Very favourable results were obtained in a locked cycle test on a deposit composite giving a recovery rate of 85% of the rare earths at a concentrate grade of 50.7% TREO.
- Grinding energy requirements have been shown to be relatively low and flotation recovery and concentrate grades are high and very favourable."
