Summary. The rare earth elements (REE) are soft, silver-coloured metals that tarnish quickly in air and have high melting points. The REE range in abundance in the crust from about the same level as copper and lead down to the same levels as bismuth. There are many potential REE ore deposits in a wide variety of rocks.

Rare earth elements (REE), with their unique physical and chemical properties, are an essential part of modern living. REE have enabled development and manufacture of high-performance materials, processes, and electronic technologies commonly used today in computing and communications, clean energy and …
