Until 1948, most of the world's rare earths came from sand deposits in India and Brazil.Through the 1950s, South Africa mined most of the world's rare earths. This happened after large veins of a rare earth bearing mineral were found there. Through the 1960s until the 1980s, a mine in California was the leading producer. Today, the Indian and South African deposits still make some rare earth ...

Jun 19, 2013· Description of Certain Rare Earth Elements. Certain rare earth elements used by LSM Analytical include:.
