MnO<SUB>4</SUB><SUP>−</SUP> ions in aqueous solution were subjected to macromolecular ion flotation, a process of flotation applied for an aqueous solution containing organic or inorganic ions to be floated, macromolecular ions including macroscopic or colloidal particles with an ion exchange capacity and polymer ions, and oppositely charged ionic surfactant. The macromolecular anions examined were basic aluminum chloride, polyaluminum chloride, carboxymethylcellulose, sodium polyacrylate, sodium alginate, potassium poly(vinyl sulfate), sodium hexametaphosphate, polyphosphoric acid, polyacrylic acid, bentonite, and sodium metasilicate. As a cationic surfactant, hexadecyltri-methylammonium chloride was used. All the above substances are effective for the MnO<SUB>4</SUB><SUP>−</SUP> ion flotation, whereas low molecular substances such as Na<SUB>3</SUB>PO<SUB>4</SUB> are ineffective, when used with the cationic surfactant. Molecular models of sublate formed during the macromolecular ion flotation are proposed.
