Gravity Separation

Shaking tables, also known as concentrating tables, are devices that leverage the principles of gravity, vibration, and water flow to separate minerals from ore streams. They consist of a slightly inclined deck covered with riffles where the ore mixture is introduced. The process begins with the ore slurry fed onto the shaking table's deck.

Gravity Separation

It is well known that gravity separation efficiency decreases as the range of sizes in the feed increases [5]. This is related to the compounding effect of size and density on the weight of particles and their subsequent movement in a gravity concentrator. ... Normally, test work includes determining floats from five to eight gravity increments ...
