Flotation of pyrolusite (MnO 2) with 1x10-4M acetate The strong flotation response at pH 8.5 when the surface is negatively charged cannot be explained by physical adsorption of an anionic collector. It is thought to be due to formation of a hydroxy complex of the manganous ion MnOH .

Summary. Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid. Ferric sulfate, which is a powerful oxidizing agent, then oxidizes the copper sulfide minerals and the copper contained is then leached by the sulfuric acid formed.
