High-efficiency grinding of soft manganese ore grinding machine helps the green development of electrolytic manganese metal

Soft manganese ore is one of the main raw materials in the manganese industry, and soft manganese ore grinding mill plays an important role in the production of electrolytic manganese metal. Electrolytic manganese metal is the main intermediate product in the manganese industry and is related to many downstream applications.

First, let’s introduce the production process of electrolytic manganese metal. There are two main processes: electrolysis and thermal methods. The electrolysis method is commonly used now. The specific process is to use manganese ore represented by pyrolusite as raw material, first grind it through a pyrolusite ore mill to about 120 mesh, then react with inorganic acid (commonly used sulfuric acid), heat to obtain a manganese salt solution, and add oxidant Oxidation and neutralization are used to remove iron, sulfide purifier is added to remove heavy metals, and then filtered and separated, and electrolytic additives are added to the solution to serve as electrolytic solution. Then inject the manganese sulfate water-soluble electrolyte containing ammonium sulfate into the separator electrolytic cell, connect the direct current, and metal manganese is precipitated on the cathode plate, and oxygen is precipitated on the anode plate. The cathode plate is periodically replaced, and the electrolysis product is passivated and washed with water. , drying, peeling and other treatments, and finally obtain metallic manganese.

With the participation of soft manganese ore grinding machine, the obtained metallic manganese is metallic electrolytic manganese. Its main function is to be used in the iron and steel metallurgical industry. It is used as a deoxidizer and desulfurizer for iron and steelmaking, and can also increase the hardness of alloy materials. , such as manganese-copper alloy, manganese-aluminum alloy, 200 series stainless steel, etc. About 90% of manganese is used in iron and steel metallurgy, and the remaining 10% is used in batteries, chemicals, electronics, agriculture, environmental protection, medicine and other fields.

Among them, the application of electrolytic manganese in the battery industry includes manganese batteries and lithium-ion battery cathode materials. The total consumption in 2021 will account for about 2%, of which the iron consumption in lithium-ion batteries will account for about 0.5%. Among them, new manganese-based cathode materials are the most widely developed, and it is expected that the amount of manganese used in lithium batteries will increase more than 10 times from 2021 to 2035. The application of manganese in lithium battery cathode materials is mainly lithium manganate and lithium nickel cobalt manganate (ternary materials). Benefiting from the rapid growth in shipments of ternary cathode materials and lithium manganate materials, the amount of manganese used in lithium battery cathode materials is expected to exceed 300,000 tons in 2025. In 2035, the amount of manganese used in the lithium battery field is expected to account for 5% of the overall demand for manganese. . This is also a new direction of application development of electrolytic manganese. HCM Hongchen Machinery, a manufacturer of soft manganese ore grinding machine, said that the prospects are promising.

Metal electrolytic manganese has broad prospects in the lithium battery industry, and the purity requirements for soft manganese ore powder are also higher. Correspondingly, the soft manganese ore grinding mill is particularly critical in this. The grinding roller of HCM Hongchen Machinery soft manganese ore grinding mill has good wear resistance and less contact surface with the material, which can ensure the purity of the material and reduce pollution. Its performance is stable, it can be started continuously, and the failure rate is low. It is an ideal soft manganese ore powder processing equipment.
