An active natural manganese dioxide mineral for use in dry battery cells is produced from a natural manganese dioxide ore by reacting the ore or a preconcentrate thereof with a solution of an acid. The acid reacts with the carbonates, such as calcium carbonate, to produce water-soluble salts which are then washed away. The resultant mineral can have an MnO 2 content of 80% by weight or more.

High-grade manganese dioxide from low-grade ores
Pure manganese dioxide was successfully produced from low-grade manganese ores. The adopted technique consists of calcining the ore with ammonium sulfate, followed by leaching to extract the soluble manganese sulfate. Pure manganese sulfate solution was converted into the corresponding carbonate, nitrate and finally dioxide. The product obtained was evaluated both physically and chemically.
Activated manganese dioxide is prepared by chemical treatment of natural ore (roasting, sulfuric acid treatment). The CMD type may be obtained either as a by-product of an oxidation process with potassium permanganate or by thermal decomposition of other manganese compounds followed by oxidation.
