The Kelsey Centrifugal Jig (KCJ) operates at up to 40 times gravitation acceleration in order to extend the separation range of gravity separation down to less than 40 μm. The Kelsey Centrifugal Jig utilizes the Harz design which is divided into two parts, the top section of heavy mineral (ragging) above a screen, and the jig chamber filled ...
The Benefits of Using Gravity The leading suppliers offer their outlook on the current state of gravity-separation technology By Simon Walker, European Editor With its Apic jigs, Delkor is now the lead supplier of jigging technology within the Tenova Mining & Minerals group.
Advantages of froth flotation separation. ... A jigger is one of the main pieces of equipment in the gravity separation process. The jigging process mixes gold ore particles of different specific gravity together, then stratifying these particles. The minerals with small specific gravity will be on the upper layer while the minerals with large ...
CC = 1.5 – 1.25 ( 6mm ) Jigging is a kind of gravity concentration method. This method seperates minerals of different specific gravity by their relative movement in response to gravity and ore or more other forces the latter often being the resistance to motion offered by a viscous fluid, such as water or air.
Gravity separation techniques have been in use in the mineral sands industry for decades; from the Reichert cone to tables, Wright sluices and the Kelsey Jig, all attempting that elusive perfect gravity separation. Just as the gravity separation ... advantages and disadvantages of the separation …

In the jig the separation of minerals of different specific gravity is accomplished in a bed which is rendered fluid by a pulsating current of water so as to produce stratification. The aim is to Figure 10.1 Hand jig The jigging action It was shown in Chapter 9 that the equation of
Gravity separation is a physical process which consists of the separation of different mineral types in the ore from one another based on differences in their specific gravities using the force of gravity, which can be influenced by one or more of other forces such as centrifugal force, resistance to motion by a fluid (e.g. air, water) etc ...
Jig Separation. Jig is important gravity separation equipment in the wolframite concentrator.Generally wolframite separation uses three-stage jigging, which is screening all qualified ore into three levels of coarse, medium and fine to enter the jigging operation.The upper limit of particle size in the coarse-grained jigging is 13mm, generally ...
