FIELD: hydrometallurgy, chemical technology. ^ SUBSTANCE: invention relates to the leaching reaction of manganese from manganese-oxide ores. Solution used for leaching manganese-oxide ores contains the following components, wt.-%: sulfuric acid, 19.0-20.0; ethylene glycol, 30.0-80.0, and water, the balance. Using the proposed solution that is stable in strongly acid media and at high temperatures (200°C) provides enhancing the selective rate of dissolving manganese oxides from depleted manganese-oxide ores. Invention provides the complete dissolving manganese oxides based on surface reduction of manganese dioxide. ^ EFFECT: improved and valuable chemical properties of solution. ^ 1 dwg, 2 ex |
