| Abstract: | This paper introduce the react mechanism and technology conditions of the two-ores method with low grade pyrolusite. On the appropriate technology conditions, utilize the pyrite and sulfuric acid direct reducing leaching low grade pyrolusite which the manganese content is approximately 25%, the leaching ratio is above 93%. This technology has some advanstages, such as saving energy, low production cost, strong practicability, high recovery of Mn, and break a new route for utilization of the low grade pyrolusite. |
