Ganzhou,being the birth place of Chinese tungsten industry, is extremely rich in tungsten source. So when tungsten is talked about, people will naturally focus their eyes on Ganzhou, just like that oil will remind people of Middle East.

Tungsten,as a rare and refractory metal, is an important strategically metal. As estimated the tungsten content in stratum is only I in the grade of ppm. But it is very rich in China. 65% of total tungsten deposit in the world is in China. It ranks the first in the world. From stratigraphical analysis the tungsten content in stratum of Ganzhou is 9.53-12 ppm and this is more than 7 times over the world average value of 1.33 ppm. The deposit of tungsten and the output of tungsten concentrate in Ganzhou, each take 30% that of total in China. Among them the deposit of high grade wolframite takes as much as 70% that of total in China and 60% in the world. So Ganzhou is called as "Tungsten capital of the world".

Tungsten industry in Ganzhou has contributed greatly to the social and economical construction of China either before or after the establishment of the PRC. It's a centurial hardship for tungsten industry in Ganzhou experiencing the development stage from nothing to powerful, from little to large. After tens of years'construction and developing, a great change has been taken place in Ganzhou and its tungsten industry has become the first main industry branch whose sales value is more than RMB10 billion. Ganzhou is transferred from main production area of tungsten concentrate to that of metallurgical products and is now transferring to that of value added tungsten products. The fast development of tungsten industry in recent years is only one example for the rapid economical development of Ganzhou.

Preface

Ganzhou is located in the south of Jiangxi province and the headstream of Gan River in China. Luo Xiao, Nan Lin and Wuyi Mountains join here. It has a very special geological structure and favorable conditions for the formation of minerals. It is rich in non-ferrous metals, especially in tungsten. GanZhou is called "The Tungsten Capital of the World" for its high-grade tungsten resource.

GanZhou is the birthplace of tungsten in China. It has been 100 years since tungsten was discovered in Xihuashan mine in 1907 in Dayu. In these 100 years, Ganzhou made great efforts in the development of tungsten industry. So it has been playing an important role in China and even in the world tungsten industry.

Through the development of recent several decades, Gan Zhou has become a distributing centre of tungsten products in Jiangxi and even in China. In recent years, a number of tungsten enterprises have developed rapidly with GanZhou government's encouragement and support. Tungsten industry in Ganzhou has entered a new developing stage.

The year of 2007 is the centennial of tungsten industry in Ganzhou and in China. We will look back on the history and the development of the tungsten industry in the one hundred years, and strive for its higher level by innovation.

The Back-View

In 1932, China Tungsten Ore Company was founded in Yudu. Central bank president Mao Zemin was appointed as the general manager. The company supplied 7,890 tons of tungsten concentrate, which was the main source of the financial income of RMB 6.2 million. It contributed greatly to the social development at that time.

I. The discovery and early development of tungsten (1907-1949)

The German missionary Mr. Wilhelm discovered tungsten in 1907 in Mount Xihua of Ganzhou where is the first place that tungsten was discovered in China. It was from then on that China's history of extracting tungsten began. From 1907 to 1914, the annual output of tungsten ore was less than 20 tons, only accounting for about 0.24% of the world's output. In 1917, tungsten ore was discovered in Dayu, Chongyi, Quannan, Dingnan and Shangyou County. The local people started mining tungsten ore. By 1918, the output of Ganzhou's tungsten ore was more than 10,000 tons, taking up 60% of the whole world's output. Afterwards, tungsten ore was discovered in Yudu and Ganxian. The government then paid great attention to the abundant tungsten resources in Ganzhou. In 1929, the first official geology report on tungsten, Gannan Geology and Mineral Survey Report was composed in Ganzhou.

In later 1930s, the KMT government carried out the system of state -monopoly purchase and marketing of tungsten mines and set up a tungsten administrative office of resource committee in Ganzhou. A magnetic separator was imported from Germany to dress high-tin tungsten. To some degree, Tungsten mines in Ganzhou played an active role in enhancing the economic strength.

In 1940s, tungsten factories in Ganzhou started its mechanizing production.  Some simple technologies were adopted in production.

As to the geology exploration, the geology institute successively compiled "Gannan Tungsten Mine Records", "The past and present of Jiangxi Tungsten Industry", "Deep Research of Gannan Tungsten Mine" and so on.

In this period, the output was 250,000 tons of concentrate, which were mainly produced by handwork.

II. The basic construction of tungsten industry in Ganzhou(1949 -1981)

Mining area

After the year of 1949, Chinese government put great importance on tungsten mine production in Ganzhou. The non-ferrous metal general administration of heavy industry ministry was set up in 1950, with Jiangxi sub-bureau and southern Jiangxi area administrative office in Ganzhou. Daji Mountain, Guimei Mountain, Pangu Mountain and many other mines became state-operated. In October, 1950, the first automated dressing plant (125T per day) was started to be built in Daji Mountain. In 1953, Daji, Xihua, Guimei mines and Shangyou hydraulic power station were listed in the 156 national projects in the first 5-year plan. In 1954, the government approved the expansion of Daji and Xihua and the design of Guimei, with respective processing ability of 1600T/day, 1785T/day, 1560T/day. In Daji mine, main production line was automated. In the same year in Dayu county, Hong Shui, Dang Ping ...mines were built. Since 1955, all mines started to use wet drill and fan ventilation to improve automation level and protect miners' health. In May 23, 1975, the national news paper "People's Daily" and Central Radio reported no silicosis had been found for 20 years.

By the end of 50s, the local government started to operate tungsten mines. Tungsten industry in Ganzhou was combined by local and state-operated mines.

There appeared many advanced collectives and individuals in this period.

During the 30 years, 570,000 tons of tungsten concentrate were supplied.

Exploration

The state also put emphasis on tungsten resource exploration. No.908 and 909 geologic exploration teams were established in 1952. There were 6 large tungsten deposits (Xihuashan, Dajishan, Pangushan, Tieshanlong, Piaotang, Huamei'ao), 17 middle deposits and 20 small deposits and other 200 smaller tungsten containing mines in Ganzhou.

Smelting, processing and related industries

In 1952, Dayu Tin Plant produced composed scheelite successfully by using sintering method.

In 1958, Ganzhou Concentration Plant was established and started its production. After 1963, tungstic acid, APT, W powder, WC powder and cemented carbide could be produced too.

Then "Umbrella" brand APT produced by Ganzhou 801 Factory was sold to Japan, US, UK and France. But the
