- ore mixture gravity beneficiation gold
The content of gold in the ore is extremely low. In order to extract gold, we need to crush the large ore rock into small pieces first, grind it, and then use appropriate gold processing methods to separate the gold from the ore, get the gold concentrate. The most used gold beneficiation method is gravity separation and flotation separation.

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.
