Separation by ion flotation was rarely approached, mainly for recovering the heavy metal cations. Installation simplicity as well as low power consumption needed in order to achieve the desired separation degree are the main advantages of the method, and these considerations lead to a relatively low total cost of implementation for such systems. This paper presents a study for iodine regenerative separation by ionic flotation, in a lab-made device, from dilute aqueous synthetic solutions (20-120 ppm), which properly simulates the sea, probe or mine water. The study of iodine concentration by flotation accompanied by iodide ion oxidation to molecular iodine aimed to determine the optimal oxidant amount, Cl-2 and H2O2 reveales that the best results are obtained when the amount of oxidant has concentrations similar to the iodide ion in the solution subject for processing.
