    Heavy mineral sands are paleo dune, beach, or river deposits enriched in high density minerals such as ilmenite, zircon, leucoxene, monazite and rutile. Less commonly garnet, magnetite, sapphire, diamond and staurolite are also mined from heavy mineral sand deposits. The natural hydrodynamic processes of ancient environments sorted sands by density,which can also be seen on modern beaches as ...

    Heavy mineral sand deposits are formed by wind and water. Hard rock is eroded by rivers and wind, or if near the coast, also by waves, tides, and coastal currents. The sediments derived from these rocks are transported, deposited, and then reworked by the same processes. This reworking causes them to become sorted by density, size, and shape. This sorting can concentrate denser and heavier ...
