Rare earth elements The rare earth elements include the lanthanide group of the periodic table, and yttrium. They are principally used in hightech appliions, such as highstrength permanent magnets, and are considered as 'critical metals' ( an irreplaceable metal with a high supply risk) due to concerns regarding China's neardominant control of the market (more than 90 per cent).

12/08/2021 · For every ton of rare earth produced, the mining process yields 13kg of dust, 9,60012,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.

A rareearth mineral contains one or more rareearth elements as major metal constituents. Rareearth minerals are usually found in association with alkaline to peralkaline igneous complexes, in pegmatites associated with alkaline magmas and in or associated with carbonatite intrusives. Perovskite mineral phases are common hosts to rareearth elements within the alkaline complexes.
