In conventional operations of iron ore beneficiation by flotation, the flotation feed is deslimed to remove the 10 µm fraction prior to flotation (Filippov et al 2014), thus the unselective flocculation effect of starch does not affect the flotation selectivity. Contrary to what occurred in this study, where the pure mineral samples used for ...

Currently, most local beneficiation plants apply the gravity separation–flotation process, as shown in Fig. 10. The raw ore is grounded to − 200 mesh, which accounts for 92 %, and a shaker is used to remove the slime and some light gangues, such as quartz, feldspar, and mica, to achieve pre-desliming and preliminary enrichment of bastnaesite.
