• Macromolecular ion flotation of Fe<SUP>3+</SUP>, Cu<SUP>2+</SUP>, and Ni<SUP>2+</SUP> ions was studied using macromolecular ions such as sodium metasilicate, sodium polyacrylate, sodium carboxymethylcellulose, sodium alginate, and sodium cyclo-hexaphosphate (SCHP) together with hexadecyltrimethylammonium chloride (HTAC). Diagrams of floatability <I>vs.</I> composition of macromolecular ion and HTAC, and floatability <I>vs.</I> pH at fixed composition of macromolecular ions and HTAC were constructed. Regions of optimum composition and pH for the flotation were determined and tabulated. Maximum floatabilities greater than 95%, some attaining nearly 100%, in the alkaline region were obtained for most of the systems, except for the system Fe<SUP>3+</SUP>–SCHP–HTAC which showed its maximum floatability, 91.7%, in the acid region. Metallic ions are considered to be combined as hydroxides with macromolecules which are then floated.
