Introduction to manganese

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.

Application 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.

Stage I: Crushing of raw materials

The large Manganese material is crushed by the crusher to the feed fineness (15mm-50mm) that can enter the pulverizer.

Stage II: Grinding

The crushed Manganese small materials are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.

Stage III: Classifying

The milled materials are graded by the grading system, and the unqualified powder is graded by the classifier and returned to the main machine for re grinding.

Stage V: Collection of finished products

The powder conforming to the fineness flows through the pipeline with the gas and enters the dust collector for separation and collection. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then packaged by the powder tanker or automatic packer.
