Metallic molybdenum was found to be a relatively late element and was only extracted from molybdenite by Swedish chemists in 1792. Because the molybdenum metal has the advantages of high strength, high melting point, corrosion resistance, abrasion resistance, etc., the use of metallic molybdenum has been widely used in the industry. There are many classifications of molybdenum ore, which are roughly divided into the following categories.
One, a single molybdenum ore
Such as Liaoning Yangjiazhangzi Molybdenum Mine, Shaanxi Jinduicheng Molybdenum Mine, Henan Luanchuan Molybdenum Mine, Fuyang Molybdenum Mine, Yechangping Molybdenum Mine, Jilin Daheishan Molybdenum Mine, Lanjiagou Molybdenum Mine, Huangshan Molybdenum Mine The Qingtian molybdenum mine is a single molybdenum ore.
Second, copper molybdenum ore
Molybdenite in ore is symbiotic with various copper sulfide minerals such as Dexing Copper Mine, Baoshan Copper Mine, Xiaosigou Copper Mine, Linjiang Copper Mine and Xianlin Copper Mine. Jinduicheng also belongs to this category.
Third, tungsten molybdenum ore
The ore molybdenite is coexisted with tungsten ore, among which tungstotungsten, ore tungsten mine, Wenshui tungsten mine, Dajishan tungsten mine, Xihuashan tungsten mine and Mituwo tungsten mine are symbiotic with wolframite; The symbiotic mines with scheelite include the Luanchuan Mo deposit and the Shizhuyuan tungsten and molybdenum deposit.
Fourth, carbon copper molybdenum ore
This type of ore is also common in foreign countries. The ore contains organic carbon and carbonaceous shale. Jinkouling’s molybdenite is co-occurring with carbonaceous siliceous shale. This carbonite is black, dense, massive and hard-bearing. It contains 2.94% carbon, has a density of 2.73g/m 3 , and carbon is in a dispersed state. Not combined with minerals. The carbonaceous shale consists of microcrystalline quartz, fine carbonaceous particles, small amounts of ferrite particles, and muddy chlorites. The carbon particle size is 0.0017-0.064. Since carbonaceous shale and molybdenite are buoyant, carbon-molybdenum separation is required.
Another type of molybdenum ore is vanadium uranium molybdenum ore Molybdenum is present in secondary vanadium crystals in vanadium uranium ore, and its particle size is small and difficult to float. The carbonaceous vanadium uranium-molybdenum ore contains 15% to 25% carbon, which is the pigment of local people's kilns. This kind of ore is very difficult to choose and can only be chemically beneficiated.
