An overview of one of the regolith-hosted rare earth element deposits (a type of Rare Earth Element mine) in South China [1]. Regolith-hosted rare earth element deposits (also known as ion-adsorption deposits) are rare-earth element (REE) ores in decomposed rocks that are formed by intense weathering of REE-rich parental rocks (e.g. granite, tuff etc.) in subtropical areas.

In June 2024, Rare Earths Norway found a rare-earth oxide deposit of 8.8 million metric tons in Telemark, Norway, making it Europe's largest known rare-earth element deposit. The mining firm predicted that it would finish developing the first stage of mining in 2030. [106]
The largest deposit of rare earth metals discovered in Europe was announced by LKAB in January 2023 to be at Kiruna. The rare earth elements have been known about at this location for over 100 years and studied in detail before. [16] [17]
Australia, the U.K. and the U.S. are all boosting capacity for refining rare earth metals. China has a stranglehold on the world’s supply of critical rare earths. These firms are trying to ...
The Mountain Pass Rare Earth Mine and Processing Facility, owned by MP Materials, is an open-pit mine of rare-earth elements on the south flank of the Clark Mountain Range in California, 53 miles (85 km) southwest of Las Vegas, Nevada. In 2020 the mine supplied 15.8% of the world's rare-earth production.
Kvanefjeld (or Kuannersuit), in Greenland, is the site of a mineral deposit, which is claimed to be the world's second-largest deposit of rare-earth oxides, and the sixth-largest deposit of uranium. [ 1 ] [ 2 ] There are also substantial sodium fluoride deposits, and Kvanefjeld is thought to be one of the largest multi-element deposits of its ...
This discovery alerted geologists to the existence of a whole new class of rare earth deposit: the rare earth containing carbonatite. Other examples were soon recognized, particularly in Africa and China. The exploitation of this deposit began in the mid-1960s after it had been purchased by Molycorp (Molybdenum Corporation of America). The ...
Round Top is known for containing rare-earth elements, including the largest deposit of heavy rare-earth elements in the United States, estimated at over 1 billion tons. [5] The rare-earth elements contained in the mountain can be used to build energy and defense applications as well as electronic devices, lasers, in oil and gas drilling, water ...
