The collection first order rate constant of a flotation column was investigated as a function of bubble size within ranges commonly seen in industrial column flotation practice. The experimental work was done in a 2.5 cm diameter glass column. High purity minerals (silica, pyrite and galena) were used for the test work.

These results indicate that larger bubbles are formed in the pulp zone of the flotation column when solids are present. A similar behaviour can be seen in Figure 16, which shows that for the two-phase system, the lower frother concentration leads to higher bubble local velocities, and the bubble local velocities remain constant at all airflow ...
