The reduction of higher manganese oxides (MnO2, Mn2O3 and Mn3O4) takes place in the upper part of the blast furnace. The reduction process of higher manganese oxides is exothermic and contributes to maintain a relatively high temperature of the top gas. In some cases additional cooling of the furnace top is introduced to limit the temperature.

May 08, 2012Manganese dioxide, the black substance used in the preparation of oxygen, has the formula MnO2. When this substance is heated oxygen is set free, but the metal manganese is not liberated; instead, a different oxide of manganese containing less oxygen is produced. The equation representing the reaction is 3MnO2 = Mn3O4 + 2O. Classes of reactions.

Polymetallic nodules contain rich concentrations of manganese, nickel, copper, and cobalt. They are found in abundance in a few ocean basins, most notably the Clarion-Clipperton Zone (CCZ), a great abyssal plain as wide as the continental United States that lies 4,000 to 6,000 meters below the surface of the eastern Pacific Ocean.

Why Does Manganese Green Sand Can Remove Iron Ion from

The manganese green sand (MnO2≥35%) is commonly used in the deferrization, demanganization of drinking water, siphon filters in water plant and filter tanks. The manganese green sand (MnO2≤30%) is applied to the deironing of sewage whose iron content is less than 20mg/L. The manganese green sand under 30% is recommended to apply to industrial water treatment.

Similar to iron, the manganese removal by physical-chemical way, can be carried out by the oxidation of Mn 2+ in Mn 4+, which precipitates then in manganese dioxide (MnO 2). The precipitation is then separated from water by filtration on sand. The only difference (with the iron), is in the reagent used.
