What is Manganese

Manganese has a wide distribution in nature, almost all kinds of minerals and silicate rocks contain manganese. It has been known that there are about 150 kinds of manganese minerals, among them, manganese oxide ore and manganese carbonate ore are important industrial material, have the highest economic value. The majority component of manganese oxide ore are MnO2, MnO3 and Mn3O4, the most important are pyrolusite and psilomelane. Chemical component of pyrolusite is MnO2, manganese content can reach 63.2%, usually contents water, SiO2, Fe2O3 and psilomelane. Hardness of the ore will be different because of crystalline degree, the hardness of phanerocrystalline will be 5-6, cryptocrystalline and massive aggregation will be 1-2. Density: 4.7-5.0g/cm3. Chemical component of psilomelane is hydrous manganese oxide, manganese content about 45%-60%, usually contents Fe, Ca, Cu, Si and other impurities. Hardness:4-6; specific gravity: 4.71g/cm³. India is the top producing area of manganese, other major producing areas are China, North America, Russia, South Africa, Australia, Gabon, etc.

Usage of Manganese

Manganese product including metallurgy manganese, manganese carbonate powder (important material of manganese refining), manganese dioxide powder, etc. Metallurgy, light industry and chemical industry have different requirement of manganese product.

Manganese Powder Processing Technological Process

Phase one: raw material crushing Manganese blocks will be crushed to 15mm-50mm fineness by crusher.

Phase two: grinding Crushed manganese material will be sent to the storage hopper by the elevator, and than the feeder will send the material to the main mill for grinding.

Phase three: classifying Ground material will be classified, coarse powder will fall back to the main mill to be ground again.

Phase four: production collecting Qualified powder will flow with the air and be collected in the dust catcher, then the finished powder will be transported to the product storage bin through discharge port. Lastly, the powder will be loaded by tank car or packed by packing machine.
