Tungsten Ore Classification

Introduction of Tungsten Ore
Global tungsten ore reserves are relatively abundant, and more than 20 types of tungsten minerals and tungsten-bearing minerals have been discovered, namely, wolframite group: wolframanganese, wolframite, wolframite; scheelite group: scheelite (chalcocite), molybdenum scheelite, copper scheelite; tungsten-warp minerals: tungsten-warp, hydrotungsten-warp, high tungsten iron wreath, yttrium tungsten-warp, copper tungsten wreath, hydrotungsten-aluminum wreath; uncommon tungsten minerals: tungsten-leadite, plagioclase wolframite, zinc-tungstenite, molybdenum-tungsten-leadite, tungsten bismuthite, antimony tungsten pyrochlore, titanium yttrium thorium ore (containing tungsten), sulfur tungsten ore and so on. Although more than 20 kinds of tungsten minerals and tungsten-containing minerals have been discovered, only wolframite and scheelite have economic value for mining.

Introduction of Tungsten Ore
The global tungsten ore reserves are relatively rich, and more than 20 kinds of tungsten minerals and tungsten-bearing minerals have been discovered, namely, wolframite family: wolframanganese, wolframite, wolframite; scheelite family: scheelite (chalcocite), molybdenum scheelite, copper scheelite; tungsten-warp minerals: tungsten waffle, wolframite, scheelite, yttrium tungsten, copper tungsten waffle, scheelite-aluminum ore; uncommon tungsten minerals: tungsten-leadite, plagioclase tungsten-leadite, tungsten zinc, molybdenum tungsten-leadite, tungsten bismuthite, antimony tungsten pyrochlore, titanium yttrium thorium ore (containing tungsten), sulfur tungsten ore and so on. Although more than 20 kinds of tungsten minerals and tungsten-containing minerals have been discovered, only wolframite and scheelite have economic value for mining.

Wolframite
Wolframite is also called wolframite-manganese-iron ore because it contains different proportions of ferrotungstate and manganese-tungstate, accounting for about 30% of the total tungsten ore resources in the world. If the iron content is high, it is called wolframite, and if the manganese content is high, it is called tungsten-manganese ore. The color of wolframite changes with the change of iron and manganese content, and the common colors are dark gray, light reddish brown, light brownish black, hairy brown and iron brown. Wolframite has a metallic or semi-metallic luster, is brittle and weakly magnetic. Wolframite is mainly produced in high-temperature hydrothermal quartz veins, and the southern part of Jiangxi, the eastern part of Hunan, and the northern part of Guangdong in China are the world-famous wolframite producing areas, in addition, Siberia in Russia, Myanmar, Thailand, Australia, Bolivia and so on are also the main production areas of wolframite. Wolframite is mainly used for refining tungsten and manufacturing tungstate.

Scheelite
Scheelite scheelite is a transparent to semi-transparent mineral with a granular or lumpy shape, the color changes with the molybdenum content, and the common colors are white, grey, light yellow, light purple, light brown, light red, green, etc. It has a greasy luster or glassy luster, and it accounts for about 70% of the total tungsten ore resources in the world. Scheelite has luminescence, with light blue to yellow fluorescence under ultraviolet light irradiation.
Scheelite is mainly produced in contact account deposits, high-temperature hydrothermal veins and cloudy quartz rocks. China's Hunan Yaogangxian is the world famous scheelite origin, in addition, China's Jiangxi Dageng, Hunan Dashunlu, Yunnan Wenshan and other places, as well as the south of North Korea's Sangtang, Germany's Saxony, the United Kingdom's Cornwall, Australia's New South Wales, Bolivia's north and the United States of America's Nevada and so on is also the main source of scheelite. Scheelite is mainly used to produce ferro-tungsten, but also to make permanent magnets.
