Statistical Compendium - RARE EARTHS

Rare-earths production is derived from the rare-earths ores bastnasite, monazite, xenontime, and ion-adsorption clay. Bastnasite is the world's principal source of rare earths and is produced in China and the United States. Significant quantities of rare earths are also recovered from the mineral monazite.

Rare-earth element - Wikipedia

Rare Earth Ore Classification. Classification of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classification that follows analogous categories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host, or are related to, REE ores are carbonatite and phoscorite, igneous rocks composed principally of ...
