| Abstract Scope |
In flotation systems, the retained gas (Eg) represents the volume of gas present in the cell, relating the contact efficiency between bubbles and species to be separated. This study characterizes the behavior of Eg in aerated equipment with a ceramic disperser. Tests were performed with and without frother agent [e] (pine oil) from 10 to 60 ppm, superficial gas velocities (Jg) from 0.1 to 2.0 cm/s and liquid (Jl) from 0.12 to 0.28 cm/s. The results show that Eg increases with Jg, reaching 30% v/v at 60 ppm [e], Jl of 0.28 cm/s, the bubble diameter (Db) was estimated with the Drift flux model, it was found that it decreases with Jg and practically remains unchanged from 0.8 cm/s, with an average Db of 0.092 cm. The largest bubble surface area (Sb) was 123.62 s⁻¹. These results demonstrate the physical potential of the device for application in environmental remediation. |
