Tungsten is an important strategic metal, widely used in modern technology in pure metal state and alloy state. The pure metal of tungsten is silver-white and has high hardness, strength and wear resistance. Alloy steel, tungsten carbide-based cemented carbide, wear-resistant alloy and strong heat alloy are the main alloying states of tungsten. Tungsten is widely used in electrical, metal rolling, machining, geotechnical engineering, aerospace, military, etc. At present, the main uses of tungsten are in the manufacture of cemented carbide, filament, high-speed cutting alloy steel and heat-resistant special steel, rocket propeller nozzles and firearms. Therefore, the tungsten ore beneficiation process is becoming more and more important.
