As we all known, the bonding force between atoms of molybdenum wire is very strong, it has high strength, small expansion, high conductivity and good heat dissipation at normal temperature and high temperature. The use of molybdenum wire can also be recycled, and the waste molybdenum wire is recycled.

Especially the molybdenum obtained from the spent catalyst occupies an important position in the production of molybdenum. It is known as the second largest source of molybdenum supply. The first major source is by-product molybdenum, and the second largest source is molybdenum production.

However, due to the variety of molybdenum waste, the waste molybdenum wire needs to be oxidized, roasted and acid, alkali treatment etc. the process of layer by layer can be used to refine the "Mo" metal.

Therefore, the recovery of waste molybdenum wire is the main material of refining molybdenum, regeneration methods are different, the commonly used methods of molybdenum regeneration can be achieved by sublimation, zinc melting and alkaline leaching method.

But the general recovery rate of molybdenum is 96-98%, waste recycling molybdenum wire can be used for producing molybdenum oxide, ferromolybdenum, ammonium molybdate and other molybdate. The use of molybdenum wire is only a characteristic of molybdenum wire, and pure molybdenum is a kind of insoluble rare metal, its surface is gray luster, melting point is high.
