froth flotation is an important concentration process. this process can be used to separate any two different particles and operated by the surface chemistry of the particles. in flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. in the process, hydrophobic particles become bound to the surface of the bubbles.

The link between particle size and froth stability

The Link Between Particle Size And Froth Stability

in this work, air recovery was used as a measure of froth stability to determine the flotation response of a copper tailings ore to changes in particle size distribution and superficial gas velocity. the system exhibited a maximum in air recovery, which correlates well with the local peak in dynamic froth stability presented in previous work.

Electrolytic Flotation Of Pyrite, Journal Of Chemical

electrolytic flotation, a rather unconventional flotation technique used in effluent treatment, was investigated on pyrite; the process was enhanced by xanthate and also a cationic collector. this was then compared with classical floatability experiments. zeta‐potential measurements, under similar pulp conditions, were carried out to explain the process mechanism. the mineral flotation
