The underflow obtained in the second stage of desliming, at 35% solid content by weight, fed the flotation circuit. The rougher/cleaner flotation trials were performed using columns with internal diameters of 6", 4", and 2" and a height of 7.0 m. The effective volume of each column was 100 L, 46 L, and 13 L, respectively.

The electrolytic flotation has mainly been used for small plants with capacity between 20 and 30 m 3 h −1. In dissolved air flotation, the bubbles are produced by controlling the pressure of water saturated with air. Three main processes of dissolved air flotation include vacuum flotation, microflotation, and pressurized flotation.

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1000 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery.
