India’s rare earth reserves are estimated at approximately 6.9mn tonnes, the world’s fifth‑largest, yet much of the refining and production capability remains undeveloped. State-run firm, IREL, has been mining rare earth materials for years, which are mainly used by the atomic energy and defence units, with most supplies for other uses still imported from China. With a processing capacity of 6 lakh tons per annum, IREL produces key minerals like ilmenite, rutile, zircon, sillimanite, and garnet. It also operates a Rare Earth Extraction Plant in Chatrapur, Odisha and a Rare Earth Refining Unit at Aluva, Kerala.
