Huangyan Tungsten Deposit
Huangyan tungsten deposit, located in the central region of Zhejiang province, is a typical granite-hosted tungsten deposit in China. It is the largest tungsten resource in East China and has been mining for more than a century, since the early 20th century. The deposit is composed of two major orebodies, the first being the Main Orebody, which hosts up to 70% of the total resources, and the second being the Side Orebody, which host the other 30%, making it an important tungsten mine in East China. The total estimated size of the deposit is approximately 620 million tonnes ore, with an average grade of 0.32% tungsten.
There are several types of ore minerals that are associated with the deposit, including molybdenum, fluorite, iron, tin, and minor gold. The host rocks of the deposit consist mainly of granite and schist, which forms the orebodies within them. The deposit is distributed in two zones, namely a central zone, which is characterized by higher grades, and a peripheral zone, where the grade is lower.
The geological setting of Huangyan Tungsten Deposit is quite unique compared to most other tungsten deposits. It is a combination of residual and sedimentary tungsten deposits, as well as a magmatic ore body. This uniqune setting makes the deposit an important tungsten resource in Asia.
In order to extract the ore from the deposit, traditional methods, such as open-pit and underground miners, as well as new techniques, such as in-situ leaching, are being used. The ore extracted from the deposit is then processed and refined to produce saleable tungsten concentrates.
In addition, Huangyan tungsten deposit is also an important source of rare-earth elements and other precious metals, including molybdenum, fluorite and minor gold. These minerals are also in high demand as they are used in many high-tech applications.
The Huangyan tungsten deposit not only plays an important role in the regional economy, but also provides support to the global tungsten industry. As tungsten is an important metal that is used in many industries, the deposit serves an important role in providing raw materials around the world.
Overall, the Huangyan tungsten deposit is an important asset in East China, and it has played a significant role in the development of the region. The ore extracted from the deposit has also been important for the high-tech and industrial sectors. In addition, its presence has been of great benefit to the global tungsten industry.
