The liquid pulsates, or "jigs" up and down, causing the heavy material to work down to the bottom of the bed and the lighter material to rise to the top. Each product is then drawn off separately. Jigging is one of the oldest processes used for concentrating heavy mineral particles from the light.
This study tests the hypothesis that the minerals with superhydrophobic surfaces can be separated well at water pulsating jigs due to the associated drag reduction. For that purpose, superhydrophobic mineral surfaces were generated by spray coating the reagents on particles, and subsequent drying of particles.
A basic method for designing reasonable jig cycles for movable-screen jigs is presented in this paper. The reliability and effectiveness of the designed jig cycle was verified with tests performed on an artificial mixed material. An iron ore (12 - 100 mm) from Huashugo Iron Mine, Jiuquan Iron and Steel Company, was treated in the TJD-75 movable-screen jig …
Very fine material, less than 1/10 millimeter in diameter, can be treated successfully on jigs, if treated with coarse stuff, the concentration taking place in the small interstitial channels between the grains forming the mineral bed. For the treatment of fine stuff on jigs, close sizing is a positive disadvantage.

This paper generalizes the results of the recent theoretical and experimental investigations on the air-pulsated jigs in Japan. The pulsating mechanism is analyzed as a special vibratory system, and the jigging mechanism as a mass system subjected to the law of hindered settling. The results of investigations on the following items are reviewed: …
Froth Flotation. Flotation is undoubtedly the most important and versatile mineral separation technique, and both its use and application are continually being expanded to treat greater tonnages and to cover new areas. Recently celebrating its first centenary, flotation has permitted the mining of low-grade and complex ore bodies which would ...

This paper presents a study of particle motion in a water oscillating flow on a Jig device, which is a high yield and high recovery gravimetric concentrator device widely used in minerals processing.
Gravity Concentration — the separation of minerals by virtue of specific gravity — is one of the oldest forms of mineral processing. Whilst its relative importance has declined in the twentieth century, the high cost of alternative processes, along with the development of a range of high capacity devices has led to something of a renaissance of gravity …
A smart control system of the device is discussed. Examples of jig implementations for obtaining minerals from natural deposits and for a recovery of minerals from mine heaps are presented.
Mineral processing operators use equipment to process mineral ores until the final form or a concentrate is produced. Commonly processed minerals include gold, silver, nickel and iron ore. Mineral-bearing ore is subjected to various processes to extract the minerals. The ore is first crushed, then processing equipment (such as screens, grinding mills, …
The air pulsating jig is also called a pneumatic jigger, which is separating minerals by air compression. According to different air chamber positions, air pulsating jigs can be divided into screen side air chamber (side drum type) jigs and under screen air chamber jigs. The air pulsation jig is mainly used in coal processing. #3 Moving Jig

A fixture holds and positions the work but does not guide the tool. Whereas a jig holds, locates, and as well as guides the tool. The fixtures are heavier in construction and are bolted rigidly on the machine table. Whereas the jigs are made lighter for quicker handling, and clamping with the table is often unnecessary.
