After experiencing more than 40 years of development and construction since the founding of the People"s Republic of China, the country"s tungsten industry has had a complete industrial system ranging from mining to hard-metal alloy production, which is based on the rich tungsten resources. Now China has about 90 State-owned tungsten mines administered by county or higher-rank governments, of which over 30 are under the unified-allocation system. Besides, it also has 43 tungsten ore-dressing plants and over 100 enterprises producing intermediate tungsten products. Although rich in tungsten resources, China had possessed neither large and medium-sized tungsten ore-dressing plants nor large and medium-sized tungsten smelting and hard-metal alloy industries before 1949. Tungsten mines are the basis for the tungsten industry. In light of the distribution and development conditions of the tungsten occurrences, China has established three major tungsten production bases centered in southern Jiangxi, southern Hunan and northern Guangdong, respectively. In addition, there are tungsten mines of a considerable size in Fujian, Guangxi, Yunnan and Gansu and some small local mines in other provinces or autonomous regions of the country. The Jiangxi tungsten production base consists of 11 large and medium-sized mines under the unified-allocation system, which are the Daji Mountain, the Xihua Mountain, the Pangu Mountain, the Kuimei Mountain, cemented tungsten carbide rods the Hukeng, the Tieshanlong, the Huamei"ao, the Piaotang, the Dangping, the Xialong and the Xiaolong, and also of some other mines under local enterprises. At the end of the 1950s, three large ore-dressing plants were constructed respectively at the Daji Mountain mine, Xihua Mountain mine and Kuimei Mountain mine. In recent years, they have been technologically transformed into modernized large ore-dressing plants. Other mines also have large or medium-sized ore-dressing plants, some of which are using comparatively advanced techniques and processes in their production. The above-mentioned 11 large and medium-sized mines, all built in the 1950s~1960s and forming the principal part of China"s tungsten mining industry, have a combined ore-mining and -dressing capacity of 5.349 million tons and an integrated tungsten concentrate cemented carbide blade production capacity of 17,080 tons per year. Their output of tungsten concentrates occupies 60% of the total of the country"s mines under the unified-allocation system. Therefore, they have played an important role in the development of China"s tungsten industry, especially in the export of tungsten ore to the former Soviet Union for machinery and equipment urgently needed by the country in the 1950s.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,mobile crushers,stone crushing plant Welcome all of you to visit our official website.iron ore concentrator:http://www.hx-china.com/36.html The Hunan tungsten production base is composed of the Shizhuyuan, Xianghualing, East Hunan (Dengfuxian), Yaognagxian and Chuankou mines (which are under the unified-allocation system and affiliated to the CNNMIC) and the West Hunan mine (which is under the unified-allocation system but not affiliated to the CNNMIC), and also of many other mines under local enterprises. The Guangdong tungsten production base is made up of the Shaoguan ore-concentration plant, the Lianhuashan mine, the Nanshan mine, the Xishan mine, the East Guangdong Nonferrous Metals Co., the Dongjiang Nonferrous Metals Co., the North Guangdong Nonferrous Metals Co., the Jubankeng mine, the Jilongshan mine, the Mianhuawo mine and the Hongling mine (which are all under the unified-allocation system and affiliated to the CNNMIC) and also of some other mines under local enterprises.
