ABSTRACT:
The process of leaching manganiferous ocean nodule ores with HCl whereby the manganese and other metals present, such as iron, zinc, cobalt, nickel, copper, and like are converted from oxides, silicates or other insoluble forms to water soluble chlorides, and are thereafter separated, purified, and the manganese recovered as MnO.sub.2 by oxidation with chlorine to provide a material suitable for use in metallurgical applications, may be improved by controlling the chlorine pressure and the pH of the leaching reaction in order to first leach out the metals other than manganese; as chloride, and thereafter recovering the manganese in the form of its silicate, aluminate, oxide, or the like.
