Sand collectors also love these black sand deposits. Such heavy mineral concentrates are called placers. Gold panning is an activity used to separate gold flakes and nuggets from these placers. However, gold is not the only mineral that is mined from placers. These minerals are also cassiterite (tin ore), ilmenite (titanium), magnetite (iron,“Mineral Sands Deposits: their complexity and need for,,The term “Mineral Sands” refers to sands which contain suites of minerals with high specific gravity (> 4 Specific Gravity) known as heavy minerals. Heavy minerals occurs as disseminated, associated or concentrated deposits within the sands. Found in an alluvial (old beach or river system) environment.Critical Mineral Resources in Heavy Mineral Sands of the U,,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.
