Heavy minerals (HMs) are used in many high-tech applications (e.g. nuclear reactors, photovoltaic cells, electronics, green, and nano- and space technology), and thus global demand is increasing day by day. This review article is focused on the global distribution, genesis, economic geology, exploration and exploitation, demand (i.e. past, …
Ancient and modern coastal deposits of heavy mineral sands (HMS) are the principal source of several heavy industrial minerals, with mining and processing operations on every continent except Antarctica. For example, HMS deposits are the main source of titanium feedstock for the titanium dioxide (TiO2) pigments industry, obtained from the …
This may however be carried out in order to ease the difficulty and complexity of the mineral processing/metal extraction route, thereby feasibly reducing the metal extraction and recovery steps. 11,33 Furthermore, Gilman 34 suggested that these mineral processing and concentration techniques of HMs or mineral sands are …

Spiral density separator in a placer deposit processing plant. 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.
Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called "spalling". Before long, mechanical means were found to achieve this.
