The role and application areas of electrolytic manganese
Electrolytic manganese metal is a elemental metal obtained by acid leaching of manganese ore to obtain manganese salts, which are then sent to an electrolytic cell for electro analysis. The appearance is like iron, in an irregular sheet shape, with a hard and brittle texture. One side is bright, and the other side is rough, ranging from silver white to brown. After processing into powder, it appears silver gray; Easy to oxidize in the air, it dissolves and displaces hydrogen when encountering dilute acids. At slightly above room temperature, it can decompose water and release hydrogen gas.
effect
The purity of electrolytic manganese is very high, and its function is to increase the hardness of alloy materials. The most widely used alloys include manganese copper alloy, manganese aluminum alloy, and 200 series stainless steel. Manganese can improve the strength, toughness, wear resistance, and corrosion resistance of these alloys.
application area
Manganese and manganese alloys are one of the indispensable and important raw materials in the steel industry, aluminum alloy industry, magnetic material industry, chemical industry, and other industries. Manganese is an indispensable additive in the smelting industry. Electrolytic manganese is the main raw material for producing manganese tetroxide after being processed into powder. The magnetic material components widely used in the electronic industry are produced using manganese tetroxide. The electronic industry, metallurgical industry, and aerospace industry all require electrolytic manganese metal. With the continuous development of science and technology and the continuous improvement of productivity, electrolytic manganese metal has been successfully and widely used in various fields such as steel smelting, non-ferrous metallurgy, electronic technology, chemical industry, environmental protection, food hygiene, welding rod industry, aerospace industry, etc. due to its high purity and low impurity characteristics. The main production areas of electrolytic manganese in China are in Hunan, Guizhou, and other regions The manganese triangle at the border of Chongqing is a crucial concentration area. Due to early and rapid development, the supply of manganese ore in Xiushan and Songtao is already tight. In addition, the local government has repeatedly collected resource compensation fees and charged tens of yuan/ton outside the county. The price of ore accounts for one-third of the cost of electrolytic manganese. Mines in Chongqing, Songtao, and Xiangxi all have the phenomenon of indiscriminate mining. Currently, only half of the tens of thousands of tons of reserves are left, and the resource recovery rate is very low, only about 50%. The phenomenon of mining rich and abandoning poor is severe during mining, and the ore grade has decreased from 19% to 16%. But Guangxi has abundant ore supply, with a reserve of 100 million tons in Daxin, which can be used for decades.
