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 air flow into fine bubbles.
