Chelating surfactants have been prepared and applied as ion-flotation collectors. Metal ions are floated by scum flotation using the surfactants in a HLB range of 4-14, which are regulated by varying the alkyl group. The selective flotation from the metal ions mixture has been attributable to the smaller HLB of the metal complexes. The HLB values of 16-24 are suitable for foam fractionation and those of 1-6 are for solvent sublation.
