Separation of Rare Earth Elements

29 10 1999  Compounding the difficulties of separation were a lack of good methods for identification and assessment of purity and a lack of knowledge of the number of rare earth elements that existed The first rare earth element yttrium was isolated in 1794 by the Swedish chemist Johan Gadolin from a heavy black mineral ytterbite named for the village of Ytterby where it was found.
