Gravity Concentration

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.

Understanding the Gold Centrifuge by Comparing it with a Sluice Box

Centrifugal separation of gold experienced a regain in activity with the advent of the Knelson Bowl. This device appears extremely efficient in recovering fine gold, although very little published data are available.

Installing a gravity plant increased overall gold recovery by about 3-4% in some plants. Gravity concentration was achieved with pinched

Clamshell Dredge

gold-dredge-close-tinted-grab-filled-with-compact-sandThe grab, or “ clamshell ” type of dredge, consists of a self-filling and discharging scoop or bucket, with the necessary engine power for working this from a crane. Well-known makers of this form of dredge are Messrs. Rose, Downs, & Thompson, Limited (see illustration), and Messrs. Priestman Bros. Both firms recommend, for this purpose,

Solubility Of Gold In Mercury

solubility of gold in mercuryAlthough three rather extensive researches on the system gold-mercury have been published within the last ten years, the disagreement in the various results is most remarkable, particularly at lower temperatures. Quite recently rather precise results on the system silver-mercury, using a new type of solubility tube, have been published by Sunier
