A new method for gravity separation: Vibrating table gravity
This paper discusses recently developed gravity concentration equipment, namely vibrating table, and reports detailed descriptions of the equipment in terms of principles of design and their effects on operational parameters.Vibrating table originally combines the known physical phenomena of a teetered bed, resistance to water flow, vibration, and density differences.

Principles of Gravity Concentration
Oscillation Principle. The statement that it is desirable to operate a gravity concentration process with as dense a bed as possible is not an absolute law. It is very evident that if followed to its logical conclusion it would lead to a condition where particles would be so interlocked that no separation at all would be possible.

How Does the Gravity Separation Process Work?
The gravity separation table, or air table, is commonly used to separate particles by weight and density. But how does gravity separation work? It's quite simple: imagine pouring a mix of heavy and light materials onto a table. The heavier items would naturally settle towards the bottom, while the lighter ones stay on top.

Explain the gravity separation in ore processing.
Gravity Separation, also known as the Hydraulic Method, operates on the principle of density difference between ore and gangue. This method is particularly effective for purifying oxide ores such as hematite (Fe2O3), an iron ore. In this process, the ore is introduced onto a sloping, vibrating corrugated table featuring grooves. A stream of water is directed over the table.
