both gas rate and bubble size; hence, knowing the gas rate and the gas holdup can lead to an inferred calculation of average bubble size. Bubble size, as with other flotation machines, clearly plays an important role in column operation. Smaller gas bubbles are generally preferred. However, in primary cleaning of mineral systems with high kinetics,

Its ability to produce a very wide range of bubble sizes (0–1,000 µm) gives Pneuflot another advantage in that the same equipment can be used for all flotation stages, from rougher through cleaner to scavenger. The technology is widely accepted by coal, potash and iron ore producers, with trials having taken place for other minerals.

SIZES FLOTATION CIRCUITS Analysis of flotation is best approached through consideration of the overall process first and then of its mechanical components (flotation tanks + mechanism).An ideal system will be a circuit in a steady state supplied at a constant rate with ore having constant initial properties, a fixed optimum floatability.

Flotation is about creating the proper energy dissipation rate in the cells, to obtain optimal contact between the bubbles and the particles and extracting the minerals. "We wanted to design a machine that enabled us to increase the air volume and reduce the bubble size at the same time and simultaneously optimise energy dissipation rate.
