Manganese dioxide (MnO2) occurs naturally as the mineral pyrolusite, about 62–63, of manganese. The most important use of MnO2 is in primary Leclanché (carbon–zinc) and alkaline batteries. This material is used to obtain the spinel structure of the cathode materials for rechargeable Li-ion batteries (e.g., LiMn2O4). MnO2 needed for the production of batteries must have high purity and high electrochemical activity. Among its several allotropic forms, electrochemical activity is the highest for γ

The ferromanganese alloy is produced through the smelting-reduction of manganese ores in submerged arc furnaces. Conventional MnO2 production requires the pre reduction of low-grade ores around 900 °C to convert the manganese oxides present in the ore into their respective acid soluble forms. Using dextrin, a cheap organic reductant, the direct or complete dissolution of the manganese in the furnace dust is possible without needing high temperature pre reduction. The leachate is then purified th
