Unlike conventional flotation cells, the HydroFloat separator is operated with a minimal froth layer. This design allows for a higher recovery of coarse particles given that the particle–bubble aggregate does not need to have significant buoyancy to penetrate and move up through a froth zone of any significant depth as in the case of mechanical cells …

Turbulence leads to disruption of bubble-particle aggregates in a flotation cell. This means that the turbulence should be enough in order not to disturb bubble-particle aggregates [ 64, 65 ]. However, their impact on the graphite flotation in the presence of NBs is not well explored, which is covered in this section.

A schematic of a flash flotation cell is presented in Fig. 1, and shows two key features of flash flotation operation: 1. The presence of an internal short circuit stream, which allows any very coarse material and rocks to flow directly to the tailings outlet as a very thick slurry (typically > 60% solids). 2.

During the flotation process, hydrophobic minerals are transferred to the by bubbles. The size of bubbles has a significant influence on the capture probability of the bubbles and particles, hence affecting the flotation efficiency. Effective regulation of the bubble size is a premise for achieving a controllable flotation index.
