Ore Beneficiation
Iron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selective flocculation–dispersion. The bioprocesses are specially suited to treat fines, slimes, and waste tailings. 4. Potential applications include.
A reagent scheme for galena/sphalerite flotation
The optical microscopy images of the raw ore (Fig. 1) show the dissemination characteristics of the main sulphide minerals. Galena associates closely with sphalerite and pyrite (FeS 2) and has a grain size of approximately tens of micrometres (Fig. 1 b and 1c). Flotation exhibits more obvious advantages in the recovery of fine-grained minerals.
