With the continuous exploitation and consumption of high-quality tungsten molybdenum resources, complex tungsten and molybdenum co-occurrence mineral resources are being gradually exploited and utilized. However, the impurity content in tungsten-molybdenum products seriously affects its performance. In order to improve the performance of tungsten-molybdenum products, the complete separation of tungsten and molybdenum is necessary. Therefore, the separation process of tungsten and molybdenum is the key.

With the improvement of the integration of semiconductor integrated circuits, the size of the device has been reduced. At present, the mainstream semiconductor transistors have reached the size of 22 nanometers or smaller. In order to measure the electrical characteristics of a single small size device, the diameter of the tungsten metal probe needed to contact the device is small enough.

Tungsten zirconium alloy is a typical energy containing structure material, which is fairly stable at room temperature and has high strength, and the zirconium based elements in the tungsten zirconium alloy are induced by impact and release a large amount of heat under impact loading. The tungsten zirconium alloy fragments made of this characteristic can use its strength to penetrate through the target and produce additional damage to the target by its release characteristics. Finally, it can significantly improve the damage effect of the fragment to the target, and has a broad application prospect in the military field.

In the process of hydrometallurgy of tungsten, due to the depletion of wolframite resources, hydrometallurgy of tungsten will also turn to scheelite and artificial scheelite as the main raw materials. The production of tungstic acid from Scheelite (powder) and artificial scheelite pulp is one of the key processes. It is also an important process for further processing of deep processed products with tungsten as the main component.

In order to protect the earth's ozone layer, a zero ODP value of HFCs and HFOs has been introduced in the world, and chlorofluorocarbons (CFCs) and hydrogen chlorofluorocarbons (HCFCs) are eliminated with a zero ODP value. HFCs and HFOs have been widely used as refrigerants, cleaning agents, foaming agents, inextinguishing agents and etching agents.

The purification assembly of the electronic air purifier consists of a generating pole and a collection pole, which is made up of plastic parts and tungsten wire, the two ends of the tungsten wire are attached to the plastic parts. Therefore, the plastic parts need to be reserved for the holes and gaps to allow the tungsten wire to pass through, the gap of the wire of the tungsten wire of the same kind air purifier is larger. The dust enters the plastic parts through gaps between holes.

The existing literature on recovering tungsten from tungsten tailings has reported that the content of WO₃ in tailings is more than 0.2%, which is relatively high tungsten containing tungsten tailings, and the tungsten minerals are selected by wet leaching and flotation, which not only needs grinding, adding medicaments, high cost, but also causing environmental pollution; and using magnetism. The method of recovery of wolframite requires energy consumption and relatively high cost.

In order to improve the leaching rate of tungsten, high pressure leaching, extraction and ion exchange are generally used to improve the recovery of tungsten.

Tungsten cobalt cemented carbide is mainly tungsten. Because of the advantages of rich tungsten mineral resources in China, in the early development of hard alloy industrial process, the waste hard alloy is not paid much attention to. The upstream industry of the hard alloy is overdue to the excessive exploitation of tungsten mineral resources, the management is chaotic, the waste of resources is serious, most of the raw raw material is high quality. It is used only to produce low-grade alloys.

The tungsten bead pad for grenade is a prefabricated killing element assembled in the axial direction of the ammunition. It can provide a killing element gain of 35 to 600 pieces for the axial direction of the ammunition. The projectile structure is made of a hard aluminum alloy body with a grooved square wire. The prefabricated fragments and high-energy explosives are made of prefabricated tungsten bead pads, which make the shape of the fragments more regular, the flying angle of the fragments more reasonable, the killing power is greater, and the function of burning and arson is to improve the killing efficiency of the grenade ammunition products.
