About Molybdenum (Mo)
Symbol: Mo
Atomic number: 42
Atomic weight: 95.95
Element category: transition metal
Molybdenum metal is a silvery white, very hard transition metal, but is softer and more ductile than tungsten. Molybdenum has excellent creep resistance, low resistivity, high corrosion resistance, high thermal conductivity, and low thermal expansion.
Molybdenum (Mo) is used principally as an alloying agent in steel, cast iron, and super alloys to enhance hardenability, strength, toughness, and wear and corrosion resistance. Molybdenum is also widely used in the furnace industry for radiation screens, elements, and sintering trays.
Other uses of molybdenum are as compounds in chemical applications. For example, molybdenum disulfide (MoS2) is used as a solid lubricant and a high-pressure high-temperature (HPHT) antiwear agent. Molybdenum trioxide (MoO3) is used as an adhesive between enamels and metals.

Classification of molybdenum ores
Single molybdenum ore
The main useful components of molybdenum ore (the main useful components refer to the main components in the ore that have economic value and can be extracted and utilized independently under the current technical and economic conditions.) are molybdenum. The Yangjiazhangzi Molybdenum Mine in Liaoning, China, and the gold mine in Shaanxi Duicheng molybdenum mine, Luanchuan molybdenum mine in Henan, Ruyang molybdenum mine and Climax mine in the United States all belong to a single molybdenum ore. In my country, the reserves of a single molybdenum mine only account for about 14% of the country's total reserves.
Copper molybdenum ore
In copper-molybdenum ores, molybdenite is symbiotic with various copper sulfide minerals, such as my country's Dexing Copper Mine, Baoshan Copper Mine, Xiaosigou Copper Mine, Linjiang Copper Mine, Chile's Despitaka, and Canada's Hyland Valley porphyry copper-molybdenum deposit, etc.
Tungsten and molybdenum ore
Molybdenite and tungsten ore coexist in tungsten-molybdenum ore. In my country, the wolframite mines that coexist with Guankeng Tungsten Mine, Wenshui Tungsten Mine, Dajishan Tungsten Mine, Xihuashan Tungsten Mine, etc.; the scheelite mines that coexist with the scheelite mines include Luanchuan Molybdenum Mine, Shizhuyuan Tungsten-Molybdenum Mine, etc. .
Carbonaceous copper molybdenum ore
The ore contains organic carbon and carbonaceous shale. Molybdenite is symbiotic with carbon-containing siliceous shale. This carbonaceous copper-molybdenum ore is black, dense, massive, and hard. It contains 2.94% carbon and has a density of 2.73g/m3. The carbon exists in a dispersed state and is not Combined with minerals. Carbonaceous shale is composed of microcrystalline quartz, fine carbonaceous particles, a small amount of iron oxide points, and argillaceous chlorite. The carbon particle size is 0.0017 to 0.064. This kind of ore is very common abroad, such as the Ailan copper mine in Canada, the Xuanhua copper-molybdenum mine in my country, the Tongshan copper-molybdenum mine in Jurong, Jiangsu, the Jinkouling copper-molybdenum mine in Tongling, Anhui, and the Bainaimiao copper-molybdenum mine in Inner Mongolia. Molybdenum ore, etc. all belong to this type of ore.
Introduction to the uses and applications of molybdenum
Molybdenum application overview
Molybdenum is primarily used in the steel industry, accounting for about 80% of total molybdenum consumption, followed by the chemical industry, accounting for about 10%. In addition, molybdenum is also used in electrical and electronic technology, medicine and agriculture, accounting for about 10% of total consumption.
Alloy field
Molybdenum has the largest consumption in the steel field, mainly used in the production of alloy steel (accounting for about 43% of total molybdenum consumption in steel), stainless steel (about 23%), tool steel and high-speed steel (about 8%), cast iron and Roller (about 6%). Most of the molybdenum is briquetted with industrial molybdenum oxide and used directly in steelmaking or cast iron. A small part is first smelted into ferromolybdenum and then used in steelmaking. As an alloy element of steel, molybdenum has the following advantages: improves the strength and toughness of steel; improves the corrosion resistance of steel in acid and alkali solutions and liquid metals; improves the wear resistance of steel; improves the hardenability, weldability and resistance of steel. Hot sex. For example, stainless steel with a molybdenum content of 4%-5% is often used in places where erosion and corrosion are serious, such as marine equipment and chemical equipment.
Chemical industry
Lubricant: Molybdenum dioxide is a good solid lubricant because it has a low friction coefficient and high yield strength. It can be used normally in vacuum and various ultra-low and high temperatures. Therefore, it is widely used in gas turbines, gears, Mold, aerospace, nuclear industry and other fields.
Catalyst: Molybdenum compounds are one of the most widely used catalysts and are widely used in chemical, petroleum, plastics, textile and other industries. For example: Molybdenum disulfide has anti-sulfur properties and can catalyze the hydrogenation of carbon monoxide to produce alcohols under certain conditions. It is a promising C1 chemical catalyst; molybdenum is used as a catalyst for petroleum refining pretreatment in combination with cobalt and nickel. Other common molybdenum-containing catalysts include: molybdenum disulfide, molybdenum oxide, molybdate, ammonium paramolybdate, etc.
Pigments: Chrome yellow and cadmium yellow are the most commonly used inorganic yellow pigments in the world today. However, lead, chromium, and cadmium are all toxic. Molybdenum yellow is not only non-toxic, but also has bright color and good light and thermal stability, so it is used in In pigments and inks, plastics, rubber products and ceramics.
Electronic and electrical fields
Molybdenum wire for electric light sources has good electrical conductivity and high temperature resistance, and its thermal expansion coefficient is similar to that of glass. It is widely used in the manufacture of core wires, lead wires, hooks and other components of spiral filaments. In addition, molybdenum wire is also an ideal electrode wire for wire-cut electric discharge machine tools. It can cut various steels and carbide. Its electric discharge processing is stable and can effectively improve the accuracy of molds.

Molybdenum recycling methods
At present, there are many methods for recycling molybdenum waste, but generally the fire method is the main method, supplemented by the wet method. The common methods are as follows:
Sublimation method: This is a method based on the fact that metal molybdenum can be oxidized into molybdenum trioxide at a certain temperature and then sublimated for capture and recovery. The recovery rate can reach 98%. This method is mainly used for recycling waste molybdenum powder, molybdenum strips, molybdenum flakes, molybdenum wire, molybdenum-rhenium alloy, and high-speed steel grinding waste.
Zinc melting method: This method mainly recovers alloy elements in cemented carbide and superalloy scraps through heating, distillation and roasting, such as cobalt (recovery rate reaches 97%), molybdenum (recovery rate reaches 96.2%), tungsten (recovery rate reaches 96.2%) 98.4%).
Oxidation roasting-acid leaching method: This method is mainly used for the recycling of molybdenum-containing catalysts. The recovery rates of cobalt and molybdenum are 97% and 95% respectively.
Sodium carbonate roasting-leaching method: This method is also mainly used to recover molybdenum-containing spent catalysts, but it mainly recovers cobalt and nickel, and their leaching rates are above 90%.
Alkali leaching method: It is mainly used for the regeneration and recovery of spent catalysts containing molybdenum and nickel. The leaching rates of molybdenum, aluminum and nickel are 96.9%, 86.7% and 90.1% respectively.
