Gravity concentration is a process to concentrate the mineral of interest (in this case gold) using the difference of specific gravity of gold and gangue minerals.

Gravity concentration is the separation of minerals based upon the difference in density. Techniques of gravity concentration have been around for millennia.

Gravity concentration is the process in which separation is realized by using the differences in density of mineral particles in a certain medium or medium flow (mostly water). It is mostly used for separation of the ore in which the useful mineral has major density difference from the gangue, e.g., tungsten ore, tin ore, and alluvial gold ore ...

Gravity concentration uses the unambiguous physical property of a minerals' density which is unaffected by the external or surface chemical environment, but has been wholly or mainly replaced by flotation, hydrometallurgy, and magnetic separation during the past century due to finer sizes of liberation and less distinction between minerals' spec...

Gravity Concentration — the separation of minerals by virtue of specific gravity — is one of the oldest forms of mineral processing. Whilst its relative importance has declined in the twentieth century, the high cost of alternative processes, along with...

Gravity concentration depends on the differences in specific gravity of the mineral of interest and the gangues, the particle size of the gold minerals, and the rheological behavior of the pulp – the settling rates of the individual gold particles (Agorhom and Owusu Citation 2022). Thus, the GRG test has become an industry standard for ...
