Leaching Gold In Manganese Ore

Manganese ore leaching process

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 2 by oxidation with chlorine to provide a material suitable for .
