How Gravity Separation Works to Recover Metals and Minerals

Gravity separation has been used for centuries to separate different minerals and metals based on their specific gravity. Some of the earliest recordings of this science in practice are from Ancient Egypt as workers panned for gold in the Nile river.

What is the Alluvial Gold Mining Method?

The principle of gravity separation used for the alluvial gold mining is to separate the gold concentrate from other minerals according to the different ore weight in the original ore. The first step of the gravity process is desliming, which removes the dirt from the mineral. The second step is to screen the larger stones and remove them by the vibrating screen. The last step is to adopt the ...

Gravity Concentration in Artisanal Gold Mining

Gravity separation occurs primarily due to weight and size differences between different particles. The size of the particles is an important parameter as a large grain of a gangue mineral (e.g., quartz) behaves like a small grain of gold in a classic gravity separation process. The rate at which a particle settles in a liquid depends on the ...
