mineral processing Concentration Britannica

Mineral Processing Concentration Britannica

Gravity separation. Gravity methods use the difference in the density of minerals as the concentrating agent. In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon). Such a suspension can simulate a fluid with a higher density than water.

Mar 22, 2021 Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity

This rudimentary piece of mineral processing equipment uses pulses of water to suspend the particles in water. As the pulses dissipate, the particles settle in the bottom of the jig. Particles with a higher specific gravity (like gold) settle faster than those with a lower specific gravity, effectively separating the gold so it can be collected.
