Gravity Concentrators & Jigs Compared

A Gravity Concentrator has the bed fluidized 100% of the time.	A Jig is fluidized only 50% of the time.
A Gravity Concentrator works at 150 g forces.	A Jig works at 1 g.
Material is caused to move in a lateral movement through the Gravity Concentrator.	A Jig has a lateral movement and a vertical movement.
The Gravity Concentrator moves concentrate laterally at very near the speed of the cone and at the same time it moves the gangue being treated in a lateral vertical plane across the concentrate face.	A Jig moves concentrate down into the hutch and gangue horizontally across the bed.
Gangue in the Gravity Concentrator picks up speed as it travels through the unit and the more centrifugal speed it picks up the closer it gets to the speed of the Gravity Concentrator.	Materiel in a jig also picks up speed horizontally but as it does so it moves away from the speed of the jig which is zero and the faster it goes the less chance there is for concentration.
