NMDC Ltd may enter into rare earth minerals and beach sand mining, for which, the miner is planning to approach atomic mineral directorate (AMD) for necessary permissions. In beach sand mining, there are seven minerals called heavy minerals. Out of which, monazite contains radioactive elements like uranium and thorium. If the content of monazite is more than 0.75 per cent of the total heavy minerals then it has to be dealt by AMD which is empowered to give special permission.
NMDC, which had earlier acquired a gold mine in Tanzania, is planning to set up a pilot gold refinery in the country.
