Mining process of tungsten ore sand

Tungsten is a very important metal, it is a very hard metal with a very high melting point and corrosion resistance. Tungsten is widely used in the manufacturing of electrodes, cutting tools, high-temperature alloys, etc. The main ore of tungsten is tungsten ore. In the process of mining tungsten ore, special processes need to be used to extract tungsten. This article will introduce the process of mining tungsten ore sand for everyone. 1、 Characteristics of tungsten ore Tungsten ore is a kind of ore with high tungsten content, and its main components are Tungstate and calcium tungstate. Tungsten ore has a high hardness and usually requires processes such as crushing and grinding to break it into small particles. 2、 The process of mining tungsten ore sand 1 After crushing tungsten ore, it can be broken into small particles for subsequent processing. Crushing usually uses equipment such as jaw crushers and cone crushers. 2. Grinding and grinding is the process of finely grinding broken tungsten ore to facilitate subsequent beneficiation operations. Grinding is usually carried out using equipment such as ball mills and short end cone mills. 3. Mineral processing is the process of separating tungsten minerals from other impurities in tungsten ore. Mineral processing usually uses methods such as gravity separation, flotation, magnetic separation, etc. Gravity separation is the process of separating tungsten minerals from other impurities in tungsten ore. Gravity separation usually uses methods such as heavy medium beneficiation and centrifugal beneficiation. Flotation is the process of separating tungsten minerals from other impurities in tungsten ore. Flotation usually uses methods such as air flotation and reagent flotation. Magnetic separation is the process of separating tungsten minerals from other impurities in tungsten ore. Magnetic separation usually uses methods such as high-strength magnetic separation and weak magnetic separation. 4. During the beneficiation process, tungsten minerals in tungsten ore have been separated from other impurities, but extraction is still needed. Extraction usually involves methods such as leaching and smelting. Leaching is the process of dissolving tungsten minerals from tungsten ore. Acid leaching, alkali leaching, and other methods are commonly used for leaching. Melting is the process of melting tungsten minerals in tungsten ore. Melting usually uses equipment such as electric arc furnaces and induction furnaces. 3、 Conclusion: The process of mining tungsten ore sand is a very complex process that requires the use of multiple processes to extract tungsten. In the process of mining tungsten ore sand, it is necessary to pay attention to safety production and avoid accidents. At the same time, it is also necessary to pay attention to environmental protection and reduce its impact on the environment.
