Optimizing Flotation Cells
Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.
High-Efficiency Nanobubble Coal Flotation | Semantic Scholar
The high efficiency of a froth flotation process is limited to a narrow particle size range. Nanobubbles integrated into a specially designed flotation column expanded the particle size range for effective froth flotation as a result of increased probabilities of particle-bubble collision and attachment and reduced probability of detachment. Results …
