Flotation | SpringerLink
Flotation process is one of the most important process factors, which has great influence on beneficiating index. The flotation process must adapt to the nature of the treated materials, and different processes should be adopted for different materials. Reasonable process flow should ensure the best beneficiating index and the lowest …
