Magnetic separation exploits the different magnetic properties in ore bodies to retrieve target minerals from gangue.
The process utilises the competition between gravitation, centrifugal and friction forces, magnetic forces, and inter-particle attraction or repulsion.
All magnetite ore bodies will require some magnetic separation investigation. ALS regularly performs the following magnetic separation 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. Expert teams of metallurgists work to optimise existing magnetite beneficiation circuits, or provide crucial data for future orebody evaluation, feasibility studies, mine planning and product marketing purposes.
