About Mineral Sands

About Mineral Sands. Heavy Mineral Sands (HMS) are naturally occurring sands that contain concentrations of minerals with specific gravity of >2.85 g/cm3. Heavy Minerals include: Zircon; Ilmenite; Rutile; Monazite and Xenotime; Heavy Minerals are then concentrated by marine processes to form concentrations within beach and sand dune environments.
