  • Magnetic separation of Red Sand to produce value ...

    2. Magnetic separation of Red Sand 2.1. Dry drum. To determine if Darling Range Red Sand could be magnetically separated, a proof of concept trial was conducted using a Reading bench top magnetic separator. Analysis of the fractions ranging from 0.1 to 0.4 T indicated that magnetic separation was possible but not as efficient as hoped.
