Praseodymium was discovered by German chemist Carl Auer von Welsbach in the year of 1885. This chemist was separating praseodymium along with neodymium from the material didymium. This was how it was first discovered, but now the element of praseodymium is usually obtained through an ion exchange process from monazite sand.
Praseodymium isn't found as the free element in nature, but it is found in the ores monazite sand and bastn°site, which are both naturally occurring solid material in which a metal or rare mineral can be removed from it. In this case, the rare mineral being removed from it is Praseodymium.
