Basic introduction of manganese powder

Electrolytic manganese is a subject material of manufacturing trimanganese tetroxide, in addition, due to the high purity, less impurity, it is a good alloy element of producing stainless steel, alloying elements, high-strength low-alloy steel, aluminum-manganese alloy, copper, manganese alloy, also an indispensable raw material for welding electrodes, ferrite permanent magnet alloy elements, and many pharmaceutical and chemical production of manganese salts; newly developed damping alloy is also used manganese metal.

In recent years, the world’s aluminum industry has become the main user of the manganese metal. In the iron and steel industry, the manganese metal also can be used as deoxidizer and desulfurizer. According to statistics, the average per ton of steel consume 0.06kg manganese metal. With the advances in metallurgical technology , the efficient steel and injection metallurgy technology has been greatly developed, electrolytic manganese metal powder in the metallurgical industry has been increasing, the dosage is expanding, breaking above indicators. In recent years, due to the rapid development of special steel, in particular, the development of Chinese 200 series stainless steel, the proportion of manganese metal in metallurgy is growing. Aluminum-manganese alloy is modern building materials, the decoration engineering materials, anti-corrosion and underground engineering support material. Aluminum manganese alloy doors and windows, etc. have been gradually entering ordinary residential, greatly expanding the manganese market. Electrolytic manganese production process: Electrolytic manganese production hydrometallurgical manganese products, for many years of production practice in China, generally use the "leaching - purification - Electrolytic Production. Mainly use manganese carbonate powder and inorganic acid, manganese salt solution, add the ammonium salt is used as buffer plus oxidant and iron removal, plus vulcanizing to get rid of heavy metals, sedimentation - filtration - depth purification - filtration draw the pure manganese sulfate solution as electrolyte additives are added into the cell electrolysis, produce manganese metal.

Manganese metal is mainly used in the steel industry, an important sulfur retention of manganese in the steel-making process from the deoxy restore, easy to form alloys role. In the United States, manganese consumption is about 85% to 90% in the form of ferroalloys used in steel and cast iron industry in the form of manganese ferroalloys and manganese metal, manganese steel consumption of about 5.1kg. Most industrialized countries manganese consumption structure is basically the same. Due to the extensive use of advances in technology and the iron and steel scrap, manganese consumption in 2002 compared with 2001, the consumption of manganese ferroalloys, silicon manganese alloy and manganese metal were down 5%, 3% and 1%, respectively. With the raising the level of steel production technology, the next unit of steel production in the manganese consumption will decline further. The manganese addition mainly used in the iron and steel industry, a small amount of manganese is also used in the production of non-ferrous metals and other alloys, manganese aluminum alloy. Small amount of manganese power is also used for glaze, batteries, manganese chemicals and chemical fertilizers. Many years ago, the manganese apparent consumption was 68.9 million tons in US, a slight decrease from 692,000 tons. The same year, reserves of manganese ore fell by 9% to 151,000 tons. In manganese aluminum alloy, manganese content of 75% to 85%, the role of manganese is corrosion resistance. Manganese aluminum alloy is mainly used in the manufacture of soft drink cans, and other uses of manganese aluminum alloy is auto parts, kitchen utensils, radiator and roofing materials,etc.
