Introduction of Manganese

Manganese is widely present in various ores, but manganese-containing ores with industrial development value must have a manganese content of at least 6% and are collectively referred to as "a certain manganese ores." There are about 150 kinds of manganese-containing minerals known in nature, which belong to oxides, carbonates, silicates, sulfides, borates, tungstates, phosphates, etc., but

Hey contain There are not many minerals with high manganese content, which can be divided into the following types.

1. Pyrolusite: The main body is manganese dioxide, tetragonal crystal system, the crystals are thin columnar or needle-shaped, usually in the form of massive and powdery aggregates. Pyrolusite is a very common mineral in manganese ore and an important mineral raw material for manganese smelting.

2. Pyromanganese: It is the oxide of barium and manganese. The color of pyrmanganese is from dark gray to black, the surface is smooth, semi-metallic luster, grape or stalactite-like mass. It belongs to the monoclinic system, the crystal is relatively rare, the hardness is 4-6, and the specific gravity is 4.4-4.7.

3. Bimanganese ore: Bimanganese ore is found not only in some hydrothermal deposits of internal generation, but also in sedimentary manganese deposits of external generation. It is one of the mineral raw materials for manganese smelting.

4. Black manganese ore: also known as "trimanganese tetroxide", tetragonal crystal system, the crystals are tetragonal double cones, usually granular aggregates, with a hardness of 5.5 and a specific gravity of 4.84. It is also one of the mineral raw materials for manganese smelting.

5. Brown manganese ore: also known as "manganese trioxide", tetragonal crystal system, the crystals are biconical, and they are also produced in granular and massive aggregates.

6. Rhodochrosite: also known as "manganese carbonate", trigonal crystal system, the crystal is rhombohedral, usually granular, massive or nodular. Rhodochrosite is an important mineral raw material for manganese smelting.

7. Pyrite: also known as "manganese sulfide", the hardness is 3.5-4, the specific gravity is 3.9-4.1, and it is brittle. Pyrite occurs in large quantities in sedimentary metamorphic manganese deposits and is one of the mineral raw materials for manganese smelting.

Application Field

Manganese ore is mainly used in the metal smelting industry. As an important additive element in steel products, manganese is closely related to steel production. There is a saying that "no manganese can not make steel", and more than 90%-95% of its manganese is used in the steel industry.

1. In the iron and steel industry, manganese is used to make manganese-containing special steel. Adding a small amount of manganese to the steel can increase the hardness, ductility, toughness, and wear resistance. Manganese steel is a necessary material for manufacturing machines, ships, vehicles, railroad tracks, bridges, and large factories.

2. In addition to the above-mentioned basic needs of the steel industry, the remaining 10% to 5% of manganese is used in other industrial fields, such as the chemical industry (manufacturing various manganese salts), light industry (used in batteries, matches, printing paint, Soap, etc.), building materials industry (colorants and fading agents for glass and ceramics), defense industry, electronics industry, environmental protection, agriculture and animal husbandry, etc.
