Recovery of lithium from spodumene-bearing pegmatites
The partially purified spodumene concentrate is fed to the flotation cells for the recovery of amblygonite, quartz, and Na-feldspar. Finally, the flotation concentrate is treated in a wet high-intensity magnetic separator to remove the magnetic impurities and produce a spodumene concentrate assaying 7.25% Li 2 O [38]. The Greenbushes …

Flotation | SpringerLink
Flotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.
