A Medley of Potpourri Rare-earth element

Until 1948, most of the world's rare earths were sourced from placer sand deposits in India and Brazil.Through the 1950s, South Africa was the world's rare-earth source, from a monazite-rich reef at the Steenkampskraal mine in Western Cape province. Through the 1960s until the 1980s, the Mountain Pass rare earth mine in California was the leading producer.
