Magnetic separators are devices used in industry to exploit differences in magnetic properties between gangue and target minerals in ore bodies. The process is a physical separation of discrete particles based on a competition between gravitation, centrifugal and friction forces, magnetic forces and inter-particle attraction or repulsion. The performance of the separators is entirely dependent on the competition between the above forces.
All magnetite ore bodies will require some magnetic separation investigation. At ALS we regularly perform the following tests:
- Davis Tube Recovery (DTR) tests on stage pulverised samples
- Davis Tube optimisation tests versus grind size
- Dry or wet LIMS tests
- MIMS tests
- WHIMS tests
ALS provides large scale, continuous integrated pilot facilities for confirmation of batch test data. Our expert team of metallurgists can work with you and your consultants to optimise existing magnetite beneficiation circuits, or provide crucial data for future orebody evaluation, feasibility studies, mine planning and product marketing purposes.
