K.E.Waters, HadlerJ.J, Cilliers (Froth and Foam Research Group, Department of Earth Science and Engineering, Royal School of Mines, Imperial College London, SW7 2AZ London, United Kingdom) wrote "The flotation of fine particles using charged microbubbles": "One of the major problems in the flotation of fine particles is the decreased probability of collision between particles and bubbles, which can be improved by a reduction in bubble size."
I replied: "This is not entirely true.
Small hydrophilic and hydrophobic particles can very successfully float on the surface of the water (the surface of the water is a giant bubble. The title of the article does not correspond with its content.
Why did they examine the charge of the bubble and not the effect of the size of the bubble? "
