Shaking Tables. A shaking table is essentially a large, rectangular, mechanized gold separation device. In one corner of the table, water is added to create a slurry. This mixture is fed to the shaking table and moves down the length of the table due to the reciprocating or "shaking" nature of the device. As the table shakes back and forth ...

Low-grade ore - The gravity separation of a sample containing less of the desired mineral, and more of the waste material (low grade) is an indication according to the workings of a typical shaking table that more of the ore will end up in the tailings and middlings, and less will end up in the concentrate the data of table 3 shows.
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.

How Gravity Separation Tables Work. The gravity separation table, or air table, is commonly used to separate particles by weight and density. A separation table can be used for any dry material as it moves on a "fluidized" bed of air across the table.The separator creates eccentric motion and has an adjustable uphill tilt which separates …
1.3 Operation of Shaking Tables. Shaking table is a mechanical device that is used to test any structures under seismic or other types of dynamic loading such as step load, sinusoidal varying force, or random load. If the shaking table is designed primarily to test civil structure under seismic loading, then it is also called earthquake simulator.
The separation on shaking table, as mentioned, is controlled by many operating parameters. Manser et al. (1991) investigated the effect of the operating parameters on the performance of a shaking table using a synthetic mixture to represent a metal ore and concluded that the three operating parameters that most influence the …
