The hydrodynamics of an operating flash flotation cell
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.

Regulation of bubble size in flotation: A review
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.
