Accepted Answer

Sri Lanka’s coastal heavy mineral placers—notably the world-class Pulmoddai deposit north of Trincomalee and localized black sand pockets at Beruwala and Kaikawala—contain high concentrations of ilmenite, rutile, and zircon, alongside radioactive monazite (a phosphate of rare earth elements carrying up to 10% thorium oxide). Exploitation, concentration, and commercial handling are regulated by the Atomic Energy Regulatory Council (AERC) and Geological Survey and Mines Bureau (GSMB). Exporting bulk mineral sands requires radiological clearance certificates and export licensing to track fissile thorium and rare-earth supply chains.

Amateur mineral collection along the beach waterline is harmless, but bagging and shipping unprocessed radioactive monazite fractions triggers customs border halts.

Separation plants use cross-belt magnetic and electrostatic separators to divide magnetic ilmenite from non-magnetic rutile and radioactive zircon-monazite fractions.
