The results show that there is a measurable but relatively small effect of gas density on bubble size. The D 32 is revealed to increase proportionally as (ρ 0/ρ g)0.132. The projected impact on flotation kinetics at 4500 m versus sea level is small, of the order of 0.5% recovery loss for a bank of eight flotation cells.

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 …

Any discussion of bubble size in flotation machines must start by recognizing the chemistry/machine interaction (Cho and Laskowski, 2002). The role of frother is illustrated in Fig. 4 which follows the impact of sequential additions to a laboratory flotation cell containing process (Impala) water (no solids).

The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.
