Flotation behavior of nickel sulfide ore in a cyclonic flotation column 775 In the flotation system, the density of mineralized bubbles (ρm) is much smaller than that of the fluid (ρ), and generally speaking, the density of particles (ρp) that cannot adhere to bubbles is much higher than that of the fluid (ρ).

Flotation Reagents - Mineral Processing & Metallurgy

Under the optimum operating parameters, the oil content in the final effluent reached to the 16.49 mg/dm3 [10, 11]. But the functional mechanism of the cyclonic-static microbubble flotation column used in oil–water separation is not clear. Many parameters influence the performance of the flotation column, especially the gas holdup [12].

Experimental Studies on Column Flotation Cell

A factionally designed experiment performed in a one meter column flotation cell identified the important factors affecting the flotation of eastern oil shales. These initial tests were performed in a batch mode, and as a result, the effect of certain operating variables was observed.
