Gravity concentration equipment
Jigging(Jig) machine for Iron ore beneficiation
The jig is simple structure, per unit area of large capacity, low power consumption,Producing high-quality iron ore concentrate. The jig is again a popular choice for processing placer gold or Iron ore deposits.
The jig consists of a cell containing water with a screen on the top. Steel or stainless steel shot is placed on the screen. A rubber diaphragm located at the bottom of the cell is driven up and down by a walking beam and eccentric mecbmism.
On the up, or expansion stroke, the water column is forced through the shot bed causing the shot bed to dilate and differential particle sorting to take place, based on Stokes Law of Hindered Settling. This allows the heavier particles on or near the shot bed to settle through the shot while the lighter particles are carried onto the tails. On the down stroke these heavier particles are pulled down through the bed and discharged through the hutch concentrate valve at the bottom of the cell.
