GRAVITY CONCENTRATION
Gravity separation dates back to 3000 BC when Egyptians used the technique for the separation of gold.
The suitability of a Gravity Concentration Process is determined before it is employed for the Concentration of an ore.

Particle Size Analyzer (PSA)
Particle size analysis, particle size measurement, or simply particle sizing is the collective name of the technical procedures, or laboratory techniques which determines the size, range, the average, and/or mean size of the particles in a powder or liquid sample.

FROTH FLOTATION
Froth Flotation was initially developed to separate sulfide minerals such as chalcopyrite from gangue. Collectors and frothers are added to a slurry to attach selected minerals to air bubbles to float them to the surface to be collected as a concentrate. Many sulfide and oxide minerals can be floated.

MAGNETIC & ELECTROSTATIC SEPARATION
Minerals can be conductive or non-conductive, which allows separation (such as gold) from quartz.
Minerals have varying degrees of susceptibility to magnetic fields, which provides the ability to separate minerals. Highly magnetic minerals such as magnetite and some garnets can be separated from paramagnetic minerals such as rutile and zircon.
