The main useful component of ore (the main useful component refers to the main component of ore which has economic value and can be extracted and utilized independently under the current technical and economic conditions). For molybdenum, China's yanjizhangzi molybdenum mine in liaoning province, jinduicheng molybdenum mine in shaanxi province, luanchuan molybdenum mine in henan province, ruyang molybdenum mine and Climax mine in the United States are all single molybdenum ores. In China, the reserves of single molybdenum ore only account for about 14% of the total reserves in China.
The molybdenum molybdenum ore in the ore is symbiotic with various sulfide minerals of copper, such as dexing copper mine, baoshan copper mine, xiaotexigou copper mine, linjiang copper mine, despica copper mine in Chile, and halanwali porphyry copper molybdenum mine in Canada. Molybdenum molybdenum ore in ore is symbiotic with tungsten ore. There are gukeng tungsten mine, wenshui tungsten mine, darjeshan tungsten mine, xihuashan tungsten mine and so on. There are luanchuan molybdenum ore, persimmon bamboo garden tungsten molybdenum ore and so on.
The ore contains organic carbon and carbonaceous shale. The pyroxene ore is symbiotic with the carbonate-silica-bearing shale. This carbonate-copper-molybdenum ore is black, dense, massive and hard, containing 2.94 percent carbon, with a density of 2.73g/m3. The carbonaceous shale is composed of microcrystalline quartz, fine carbon particles, a small amount of ferroxic point and argillaceous chlorite. The carbon particle size is 0.0017 ~ 0.064. Such ores are common in foreign countries, such as Canada's aylan copper mine, China's xuanhua copper-molybdenum mine, tongshan copper-molybdenum mine in jiangsu province's jurong mine, tongling copper-molybdenum mine in tongling, anhui province's tongling jinkou mine, and bainamiao copper-molybdenum mine in Inner Mongolia.
