For more than 500 years jigs have been in use for mineral separation. Georgius Agricola first described the application of jigs in the De re metallica in 1550 (a book cataloguing the state of the art of mining, …
The Kelsey Centrifugal Jig extends the effi cient size recovery range of fi ne mineral separation processes to 10 microns by combining the principles of conventional jig technology with centrifugal force. Spinning the jig increases the gravitational fi eld, which subsequently increases the apparent specifi c gravity difference between minerals.

Our jigs are well known for having a large capacity and small footprint. Their modular design, trapezoidal-shaped bed and saw-tooth drive result in an optimal recovery and high upgrade of the valuable heavy mineral, even for the finest particles (down to 50 µm) and at low density differences. The IHC Mining jig has successfully been used for a ...
. A jigging machine is a piece of equipment that implements the jigging process. The process in which the material is sorted according to density differences, mainly in a vertically rising and falling stream of variable speed media. The difference in size and shape of the material has an effect on the result of the separation.
Abstract. The paper discusses the results of noise studies in opencast mines and analyses the noise levels produced by different machineries and its impact. Further, it focusses on the adverse ...
1 Introduction. There are a number of advantages for upgrading coal with dry jigging technology, most notably the lack of process water, which eliminates the need for fines dewatering and slurry confinement. Dry jigging eliminates the product moisture penalty associated with wet processing of thermal coals. Particulate emissions are virtually ...
Up-motion (side-motion) diaphragm jig is most the equipment for roughing and concentrating. It is wildly used in the separation of tungsten, tin, gold and other metal minerals with large density. The separation particle size is from 0.2mm to 18-12mm. The characteristics are high enrichment and large stroke coefficient.
jigs Archives Mineral Processing amp Metallurgy. WebGold Jig amp Mineral Processing Jigs. The Gold Jig or Mineral Jigs are important of all types of alluvial gold concentrating device among all gravity separation methods they are also the most complex and the practice of jigging in mineral processing is often viewed as an art rather than a science.
The ore will be fed into a vibrating screen to sort, with oversize being fed into a ball mill for additional processing and the specific sized material sent into the mineral jig. The concentrate ...
Mineral processing is an important step in the mining and extraction of raw materials. It involves separating valuable minerals from ore, which is done most efficiently through a process known as jigging. Jigging is a common method of mineral processing and involves the use of a jig, which is a type of mechanical device.
such jigs to the framework of mineral processing (e.g., the use of under-screen aeration to change the apparent density of particles, as in the hybrid jig). 2.3.
Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical …

Iron ore processing operating practices vary depending upon the the quality of iron ore deposit. For high-grade ore, dry- or wet processing can carried out and for low-grade ore beneficiation is needed to make it suitable for iron making. Typical flowcharts for processing different types of deposits and their usage is given in Fig. 2.8.
