Why is Ganzhou the capital of tungsten?

Ganzhou City is located in the south of Jiangxi Province, adjacent to Guangdong, Fujian, and Hunan. It is located on the southern edge of the mid-subtropical zone, with dense rivers, beautiful mountains and clear waters, and a forest coverage rate of 74.4%. Ganzhou is a famous historical and cultural city in China with a history of more than 2,200 years. It has rich and colorful tourism resources, quaint Hakka houses and rich Hakka customs.

Ganzhou has a superior location and convenient transportation. It has "one vertical and one horizontal" railway trunk line, "two vertical, two horizontal and two connected" highways, "three vertical and three horizontal" national and provincial highways and a The civil aviation airport is the direct hinterland of my country's Pearl River Delta and Southern Fujian Triangle and an important passage from the inland to the southeastern coast.

Ganzhou City is also one of the most important non-ferrous metal bases in China, with the largest reserves of wolframite and ionic medium and heavy rare earth minerals in China. Since the reform and opening up, Ganzhou's economy and society have developed comprehensively and rapidly, and its comprehensive strength has been increasingly enhanced. An industrial system has been formed with the tungsten, rare earth, and fluoride salt chemical industries as the pillars, with six major industries including non-ferrous metallurgy, mechanical and electrical manufacturing, and light textile processing as the leading industries. industry, the city presents a vibrant scene.

The development of Ganzhou’s tungsten industry is a microcosm of Ganzhou’s rapid development.

The unique geological structure contains rich resources

Ganzhou City is located in the eastern section of the Nanling metallogenic belt, an important metal mineralization zone in my country, with two mountains: the Nanling Mountains and the Luoxiao Mountains. Large mountain ranges meet here and have a very unique geological structure. It is this unique geological structure that makes Ganzhou a world-famous tungsten ore gathering area. The remaining reserves of tungsten ore resources account for about 30% of China's.

Ganzhou’s tungsten mineral deposits have the characteristics of concentrated reserves, multiple types of deposits, good ore quality, and many associated components. According to statistics, the enrichment of tungsten in the formations in southern Jiangxi is 9.53ppm, and some formations are as high as more than 12ppm, which is more than 7 times the average tungsten in formations in the world of 1.3ppm. The types of mineral deposits include quartz vein type, skarn type, rock type, greystone type, placer type, etc. Among them, the number and scale of quartz vein type tungsten deposits are the largest in my country and even the world. The most important type of ore is high-quality wolframite ore. This type of ore has higher grade and good selectability. Most of them are easy-to-select ores, and the ore beneficiation recovery rate is greater than 85%. The main associated elements and minerals identified in tungsten deposits are tin, molybdenum, bismuth, copper, lead, zinc, silver, beryllium, niobium, tantalum, rare earths, lithium, crystal, fluorite, etc. These minerals can generally be recycled .

Based on the mineralization mechanism of the tungsten deposit in Ganzhou City and the specific surrounding rock conditions, geologists created the "five-story" and "seven-story" models of vein tungsten deposits, that is, from the surface to the depth: Marker zone composed of fine line veins, thin vein zone, thin vein-thin vein mixed zone, thin vein zone, and large vein zone. This model has played an important guiding role in geological exploration and mine development, opening up the prospecting prospect of wolframite ore again.

After entering the 21st century, Ganzhou City was identified as a national strategic tungsten ore prospecting area. The Chinese Academy of Geological Sciences also established a geological research base and postdoctoral workstation in Ganzhou to study the development of tungsten under special geological structural conditions. The mineralization rules present exciting prospecting prospects. It is expected that the city's new resource reserves will be twice as much as the current reserves in the next five years. There is no doubt that Ganzhou's tungsten resources have huge potential and bright prospects
