The porphyry and skarn molybdenum deposits are the main molybdenum beds in China, and their reserves account for more than 40% of the total molybdenum.

Classification of molybdenum ore
1. Single molybdenum ore
Liaoning Yangjiazhangzi as molybdenum, Shaanxi Jinduicheng molybdenum mine, Henan Luanchuan Molybdenum Mine, Ruyang molybdenum ore, molybdenum ore Yechangping, Jilin Montenegro molybdenum, Lanjiagou molybdenum ore, molybdenum ore Huangshan And Qingtian molybdenum ore is a single molybdenum ore.
2, copper molybdenum ore
The molybdenite in the 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.
3. Tungsten molybdenum ore
Dan Zhonghui mining molybdenum and tungsten ore symbiosis, which wolframite symbiotic have Piaotang tungsten ore, tungsten ore pit Guanxi, Wenshui tungsten ore, tungsten ore down the mountain, West Huashan tungsten ore and tungsten ore and other cotton Figure nest; The mines that are symbiotic with scheelite include Luanchuan Molybdenum Mine and Shizhuyuan Tungsten Molybdenum Mine.
4, carbonaceous copper molybdenum ore
This ore is also common in foreign countries, and the ore contains organic carbon and carbonaceous shale . The molybdenum deposit in Jinkouling is symbiotic with the carbon-bearing siliceous shale. The carbon rock is black, dense, massive, and firm. It has a carbon content of 2.94% and a density of 2.73 g/m. The carbonaceous material is dispersed. Not combined with minerals. The carbonaceous shale is composed of microcrystalline quartz , fine carbonaceous particles, a small amount of ferrite sites, and argillaceous chlorite, and the carbon particle size is 0.0017 to 0.064. Carbonaceous shale and molybdenite are floatable, so carbon and molybdenum separation is required.
5. Vanadium uranium molybdenum
Molybdenum is present in the ore as a secondary microcrystal, and the particle size is small and difficult to float. The carbonaceous vanadium uranium-molybdenum ore has a carbon content of 15% to 25% and is a pigment for local people burning kiln. This ore is very difficult to choose and can only be used for chemical beneficiation .
