How to find tungsten ore

The types of tungsten deposits, if divided according to the combination of mineral elements, are W-(Sn, Bi, Mo), W-Be, W-(Cu, Pb, Zn, Ag), W-Nb-Ta, W-Au-Sb, W-Li, W-Cu-Fe, W-REE, and so on. Its industrial types include quartz vein-type wolframite deposits (Sawpan Pit, Guangdong, Dajishan, Jiangxi, etc.), porphyry-type tungsten ores (fine-vein infiltrated and dunite-type) (Lianhuashan, Guangdong, and Yangduling, Jiangxi), blast breccia-type tungsten deposits (Dahutang, Jiangxi), sillimanite-type scheelite deposits (Yaogangxian, Hunan; Xiangbenshan, Jiangxi; Xiaoliugou, Gansu), silica xikite-dominated layer-controlled, multi-causal stacking-type (Kakijukyuan, Hunan), and layer (Kakizhuyuan, Hunan), layer-controlled multi-causal superposition type (Daming Mountain, Guangxi), and alluvial type.

Signs for finding tungsten ore

Water system heavy sand measurement and soil heavy sand measurement. This is because wolframite and wolframite are not easy to be oxidised and decomposed during weathering and erosion, but are gathered as heavy materials at the bottom of soft sediments or soil.

2,Shell-mantle mixed-source veins brought from the depth by deep and large fractures can form porphyry-type and breccia-barrel tungsten ores; while veins from shell-source types form vein-type or yucca-type tungsten ores.

The tungsten-bearing quartz veins in the tungsten mining area are often produced in clusters and bands, and most of them have the characteristic of equidistant output. According to the horizontal and vertical zoning distribution law of tungsten mineralisation and hydraulic fracture fissure output law, the existence of hidden veins can be accurately predicted.4. The internal and external contact zones of granitic rock bodies and the surrounding rocks of rock body top cover phases, which have the parts of dacite, silica, potassic, sericite, fluorite, and sillimanite, etc, are the good places to search for tungsten ores.

4, in the silica-porphyry type of copper, molybdenum, lead-zinc, rare earth, niobium-tantalum mining area and similar stratiform type of silica distribution area, attention should be paid to find tungsten ore.

5,Because fine-grained scheelite is easy to be confused with quartz, but scheelite fluoresces light blue, while quartz does not fluoresce. Therefore, fluorescence irradiation is the most effective and fastest means to distinguish quartz from scheelite.

6. Pay attention to find tungsten-antimony-gold deposits in antimony-gold construction of shallow metamorphic rocks, such as Hunan Wuxi gold mine.
