Definitions
- the present invention also relates to a magnetic separation apparatus for beneficiation of weakly paramagnetic lithium-mica minerals from a milled feed stream containing weakly paramagnetic lithium-mica minerals, highly magnetic ferrous waste and nonmagnetic gangue.
- the process of the present invention can be used to achieve >90% recovery of weakly paramagnetic lithium-mica minerals to a concentrate.
- the process may comprise feeding each feed stream fraction ora combination of one or more feed stream fractions into a WHGMS and obtaining a paramagnetic lithium-mica mineral concentrate product stream therefrom.
- One or more, for example each, feed stream fraction may be fed, for example separately fed or in combination, into the same WHGMS, or into separate WHGMS.
- the process may comprise feeding a product stream obtained from the Rougher WHGMS into a Cleaner WHGMS to provide a fourth product stream comprising an increased concentration of paramagnetic lithium-mica minerals compared to the second product stream obtained from the Rougher WHGMS, and fourth waste stream.
- FIG. 2 shows an embodiment where the second nonmagnetic waste stream E is fed into a Scavenger WHGMS 3.
- the Scavenger WHGMS has a magnetic field strength preferably equal to or greater than the magnetic field strength of the Rougher WHGMS 2.
- the Scavenger WHGMS 3. provides a third product stream F comprising concentrated paramagnetic lithium- mica minerals, and a third waste stream G.
