Experts said the superior performance of Nd-Fe-B is a permanent magnet material is widely used in electronics, telecommunications, and other fields. The material contains about 30% of the rare earth elements (of which about 90% of neodymium, for the rest of terbium, dysprosium, etc.), some also contain 2% to 3% of cobalt element. NdFeB material in the REE uses extremely broad, economic construction and social development have an important impact.

However, because of backward production technology, the use of Nd-Fe-B in the process of production will produce about 20% of the waste, including turning block and immersion wastes. Experts suggest that the Nd-Fe-B should be discarded materials for recycling, which will not only help save resources and avoid wastage of rare-earth resources, but also to reduce industrial waste, protect the environment and meet the needs of the material at home and abroad, have significant social and economic benefits.

Relevant state departments responsible person pointed out that with the development of the electronics industry, China's excessive consumption of valuable resources should be strengthened related materials waste recycling. Judging from the current situation, the formal separation of rare earth there has been no mystery, but over the years our country has been neglected waste material recycling technology and applications research. In recent years, European and American countries have introduced "green recycling directive", the objective is also requested China's home appliances, electronics manufacturers take responsibility for recycling and related industries in China faced tremendous pressure.

It is understood that REE NdFeB waste recycling, can produce neodymium oxide, oxidation terbium, dysprosium oxide and cobalt oxide (or terbium dysprosium oxide). Neodymium oxide mainly used for laser material, special agent colored glass, ceramic glaze colors, and jewelry and colorings. Neodymium metal mainly used for Nd-Fe-B permanent magnet materials, master alloys, oxygen storage materials and combustion alloy additives. Magnetic materials led to a booming industry neodymium oxide prices, acquisitions NdFeB waste also more profitable. Some companies not only from domestic acquisitions, buying more from abroad. Experts pointed out that the industrial waste for recycling, the development of recycling economy is an important way; In carrying out waste recycling the same time, we must make good use of their raw material resources.
