(c) & (d) : The State of Kerala does not have any independent deposit of uranium. However, heavy mineral sand deposits in Kerala contain monazite. Monazite is a mineral of rare earth phosphate and it contains up to 10% thorium oxide and upto 0.3% uranium oxide.
Monazite is recovered as a by-product of ilmenite mining by the Indian Rare Earths Limited (IREL), a central Public Sector Undertaking (PSU), under the Department of Atomic Energy (DAE) and Kerala Minerals and Metals Ltd. (KMML), a PSU under the Government of Kerala. Monazite is processed for production of compounds of rare earths as well as of thorium and uranium.
