Critical Mineral Resources in Heavy Mineral Sands of the …

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.
