Effect of impeller rotational speed on the size

2006-11-1  Ahmed and Jameson (1985) studied the effect of impeller rotational speed on the flotation rate of latex, quartz and zircon particles in a small Rushton turbine flotation cell (∼2.5 dm 3). The impeller rotational speed was varied over the range 100–600 rpm, corresponding to an approximate 36-fold change in mean energy dissipation, according
