In the magnet field, nothing can really compete with Nd (Neodymium)!

Francis Wall, a professor of applied mining at the University of Exeter in the University of Exeter, said: “In terms of magnets, there really is nothing to compete with.” “So far, they are the best choice for applications.” A so-called rare earth element, a silvery metal, plays a very important role in renewable energy. When combined with iron and boron, it produces powerful magnets that are important for wind turbine generators and electric vehicle engines.

Wall explained that despite the name, rare earth elements like strontium are not particularly rare. The elements are relatively rich. Some of the elements found in the earth’s crust are the same as the elemental copper that sounds more like a passerby. The challenge is that cockroaches are largely controlled by one country.

About 85% of the world’s cockroaches come from several mines in China. The mining of Baotou in northern China has caused a toxic lake and other environmental disasters. Other places also have small mines – such as the Rainbow Rare Earth mine in Burundi and the Mkango mine in Malawi – but in general, even mines outside of China tend to send their minerals to China for processing. This is also the case with the Perth Mountain rare earth mine in California.

A huge bottleneck in mining and processing is capital. Wall explained: “There were a lot of rare earth exploration projects at the time. If you don’t invest in the next stage, these projects will gradually slow down.” Wall expects other suppliers to enter this market as demand increases. More mines will have room for development.

Neodymium, 钕 Nd, atomic number 60, atomic weight 144.24, the element name is from Greek, the original meaning is “twin”. In 1841, the Swedish chemist Mosandel obtained a mixture of strontium and strontium from the bauxite; in 1885, the Austrian wilspel separated the green strontium salt and the rosy strontium salt and determined that they were two new elements. The content of strontium in the earth’s crust is 0.00239%, mainly in monazite and bastnasite. There are seven kinds of strontium isotopes in nature: 钕 Nd 142, 143, 144, 145, 146, 148, 150, of which cesium 142 is the highest.
