Manganese carbonate

Manganese carbonate with a chemical formula MnCO3 is a cream-to-pink material that is released in small amounts, slowly and slowly in hot water over time. It is found naturally in the form of rhodochrocyte.

Applications of manganese carbonate:

Manganese carbonate for the preparation of other manganese bivalent salts, ferrites and the production of welding wires in medicine and pharmaceuticals for the production of hematinic pills, ceramic production, production of zinc metal and in agriculture as micronutrients for the long-term supply of manganese needed by the plant It is consumed. Manganese sulfate.

Manganese carbonate production method

Manganese carbonate is formed as a deposition by the reaction of Manganese sulfate with alkaline hydrocarbon soluble in water such as sodium carbonate or ammonium hydrogen carbonate.

MnSO4 + 2NH4HCO3 → MnCO3 + (NH4) 2SO4 + CO2 + H2O

After separation and washing, the resulting manganese carbonate should be dried at 120 ° C and the inert gas environment (in order to prevent oxidation).

Oxygenation of manganese carbonate: The oxidation of manganese carbonate is initially carried out by air, which is produced by the action of manganese oxide.

MnCO3 → MnO1 / 85 + CO2

The oxide is then suspended in sulfuric acid and oxidized to ᵧ-MnO with sodium chlorate.

MnO1 / 85 → MnO2

Manganese has been proposed for economic reasons and having certain physical-chemical properties as one of the strategic metals used in iron and steel industry, ferroalloy production, battery-making and ….

About 90% of manganese consumed in the world is consumed in metallurgical industries, such as the production of steel and non-iron alloys. The battery industry consumes 40 to 50 thousand tons annually, equivalent to 7.5 to 3.5 percent of total consumption. Manganese sulfate 2

Manganese rock is mainly used to produce ferromanganese, cast iron and steel. In addition to metallurgical applications, manganese also has several non metallurgical applications that include natural or synthetic dioxide in dry and chemical batteries, manganese sulfates and oxides of sulfur in animal feed and fertilizer additives in agriculture, permanganate (as oxidizing agent) , Corrosion treatment, Ceramics, Glass and Brick, Welding Electrode, Ferrocyclomechanism,

Ferrites Production, Water Treatment, Hydrometallogy, Fuel Additives and Other Substances
