Separation of heavy non-ferrous metals from dilute aqueous solutions by ion flotation

Abstract

In recent years in the literature appeared information about the possibility of using the method of ion flotation for the extraction of elements from solutions. This method is most effective for solutions of low concentrations. Thus, F. Sebba considers the ion flotation method as the main way to obtain metals from dilute solutions - even from seawater. Armour hopes to apply the process of ion flotation to extract metals from mine water, and a group of American engineers has investigated the possibility of extracting strontium from the waste water of the nuclear industry.
