“…The time required for bubbles to rise up through the liquid in the PIC column is in the order of 4.4 s, some 44 times the period required to achieve equilibrium. This estimate is also consistent with the findings of Galvin et al (1992). Hence equilibrium adsorption is a justifiable assumption.…”

“…For CTAB at 303 K, the empirical constant, a and b, are approximately equal to 2.5 Â 10 À 5 m and 6350 M À 1 , respectively (Galvin et al, 1992); however, these values are susceptible to the presence of impurities.…”

“…This expression was given by Galvin et al (1992) to calculate the recovery, R, for a continuous ion flotation column. Their derivation assumed the contribution of the surfactant via the interstitial liquid, j f C b , was negligible.…”

“…In principle, the surfactant recovery should remain unchanged for various processing rates if the feed to gas flux ratio is fixed (Galvin et al, 1992). A reduction in the degrees of freedom is thus achieved by ensuring the feed to gas flux ratio is constant in all of the experiments.…”

“…Galvin et al [66] investigated ion flotation of the aurocyanide anion, Au(CN) 2 -using cetyltrimethylammonium bromide, (CTAB) from synthetic solutions containing the dicyanoargentate anion, Ag(CN) 2 -as a contaminant. A separation factor of 8 was obtained for the recovery of gold from solutions containing large quantities of silver.…”

Foam separation has been applied to recover or remove various substances from dilute aqueous solutions in various industries because it is an environment-and cost-friendly process. The literature has been reviewed focusing on the separation of metal ions.From an operational point of view, various methods are discussed for the removal of metal ions from solution, and on the selective recovery of a specific target metal ion.The former applications are designed to purify industrial effluents, and the performance of foam separation is well proven. The latter examples are aimed at recovering valuable metals, which has been shown to be difficult due to the inherent problem of contamination in foam separation. An operation mode was developed to overcome this problem and to enhance the selectivity for separating a specific target metal from solutions containing multi-metals. The method, called continuous counter-current foam separation, was developed, and its performance was demonstrated by the experimental results for Ga(III) separation. Since both high selectivity and recovery was obtained by this method, foam separation is potentially a "solvent-free" alternative to solvent extraction.
