Mountain Pass mine - Wikipedia
The Mountain Pass deposit was discovered in 1949 by a uranium prospector who noticed anomalously high radioactivity. The Molybdenum Corporation of America bought the mining claims, and began small-scale production in 1952. Production expanded greatly in the 1960s, to supply demand for europiumused in color television screens. Between 1965 and 1995, the mine supplied most of the worldwide rare-earth metals consumpt…
