A US company has developed a new process for recovering tungsten from tungsten-containing waste. The process of the process is: firstly digesting the tungsten-containing waste material with a sodium hydroxide solution to form a sodium tungstate solution, crystallizing the sodium tungstate crystal; then dissolving the sodium tungstate crystal in the circulating mother liquor to regenerate the sodium tungstate solution; The tungsten is extracted by an organic extractant, and the ammonium tungstate is purified and evaporated to form ammonium paratungstate and a mother liquor containing tungsten, silicon, arsenic , phosphorus and molybdenum , and the mother liquor can be recycled. The advantage of this process is that the mother liquor can be recycled, avoiding the problem of releasing large amounts of ammonium salts in the past process.

1. The vibration motor has the advantages of smooth running, low noise and long
service life.
2. The material thickness, movement speed, and total amplitude can be
steplessly adjusted.
3. As our drying equipment causes little damage to material surface, it is
ideal for drying of fragile materials.
5. This drying machine uses 30 ~ 40% less energy than common drying devices.
