Heavy Rare Earth

After extraction-separation of yttrium and the heavy rare earth elements, there is a small amount of yttrium in the group of heavy rare earth elements; the next process is normally to separate the mixture of HoYErTmYbLu into two groups, HoYEr and TmYbLu, since the separation factor β Er/Tm is bigger. These two groups are further separated into pure individual rare earth element later. Get price

The Geopolitics of Rare Earth Elements

China still controls the vast majority of all rare earth production, and for some key medium and heavy rare earth elements such as dysprosium and terbium, which are necessary to produce permanent magnets in electric vehicles and wind turbines, China's control is virtually complete, with more than 98 percent of global supply.
