Parameters influencing flotation in removal of metal ions

Matis, Konstantinos
Stalidis, G.A.
Zoumpoulis, Anastasios

In this paper the main parameters affecting the flotation process, like reagents (collector, frother, flocculant, etc.) and feed concentrations, pH value of the solution, ionic strength, gas flowrate and bubbles size, as applied to the separation of heavy metals and from dilute aqueous solutions, hydrometallurgical or environmental origin, are examined. The flotation methods used, in laboratory scale, were ion, precipitate and adsorbing colloid flotation, while the necessary for the flotation process bubbles were generated by two different techniques: dispersed-air and dissolved-air. Given examples of metal ions removed include chromium, lead, zinc and arsenic; potential applications of these methods are discussed briefly.
