Flotation Mechanism of Lead-Activated Cassiterite with
3.1 Flotation Behavior. The flotation behavior of minerals using RA as a typical fatty acid collector is highly controlled by the pH of the slurry [].Thus, the effect of pH on the flotation of SnO 2 with RA was first examined. When SnO 2 was floated by 2 × 10 −5 mol/L RA, the increase in pH favored the flotation of SnO 2 (Fig. 2a). The RA molecules may be …
Optimization of High-grade Fluorspar Recovery from Rare
The flotation cell was not chosen in this study because (i) most of the grains were fine, between 15 and 30 μm; (ii) the flotation is a complex system, and changes in a single factor (e.g., equipment factor) will produce compensating effects in other factors of the system (e.g., chemistry factor and operation factor).
