3.4. Effect of cell hydrodynamics on flotation performance. Overall recovery (R O) in a flotation cell is a function of recovery in the collection (R C) and froth (R f) phase, Eq. (4), ( Dobby, 1984 ): (4) R o = R f R c R f R c + 1 - R C. The drivers of recovery are very different in these two phases.

The development of industrial protein-based mineral flotation remains to be further explored. Protein flotation has been introduced as a low-cost, non-toxic process in which proteins such as enzymes, whey proteins, etc. act as surface modifiers to achieve selective mineral separation (Dwyer et al. 2012; Merma et al. 2019).
