Predicting the metallurgical performance of a flotation cell can be done using kinetics testing and mathematical modeling. Since its introduction in 1985, the so-called compartmental model of flotation has been adopted by most modeling and simulation platforms [4, 5].This model separates the flotation cell into two zones, each with its own sub-model.

Mechanical flotation cells utilise an impellor to agitate the slurry and produce turbulent regions for bubble particle attachment, whereas in pneumatic flotation cells pulp and air are introduced together into the cell through a nozzle, also termed a downcomer, that promotes bubble-particle contact (Gupta and Yan, 2016).

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.

The success of flotation is influenced by flotation key parameters. The aim of this study was to present a set of small-scale screening methods for the key flotation parameters particle size, particle hydrophobicity, bubble size and direct particle-bubble interaction. Experiments were performed with the model microorganism S. cerevisiae.
