Neodymium is primarily mined as part of a conglomerate with other rare earth elements in the monazite and bastnaesite mineral deposits. Historically, a single mine in California produced most of the world's rare earth minerals, but since the early 90s, China has become the world's primary source. At its peak in 2011, China supplied over 95% ...
