Coarse particle flotation: A review
In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse …

Coal Flotation
Flotation tests were carried out in a 1.5 L lab flotation cell, at 150 g solids/L pulp density. Both flocculants were found to strongly depress coal flotation: the higher the flocculant dosage, the smaller the yield of the concentrate, higher its ash content, and lower ash content in the flotation tailings.
