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. Gold jigging has been referred to as being probably the most complex gravity operation because of its continuously varying hydrodynamics.
Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density). The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed. There are many variations in design; however the

Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.
For for Coarse Gold Recovery (>2mm), here is an easy to build hand-operated mineral jig. This jig can be used for batch ‘jigging out’ gold from oversize (>10 mesh) from pre-sluicing or panning rejects as occasionally there will be coarse nuggets present in the oversize rock and this can-be-homemade jig works as a simple hand operated device especially developed to recover these nuggets.
The smallest gold particles (which are most difficult to recover) are directed into low-profile riffles along the bottom of the sluice box which have long been proven to be very effective at trapping fine gold. 2) Size and volume: Jigs are available in different types and sizes. Generally, a certain size of jig is designed to process a given
7/11/2019· Gold mining can use several different techniques, depending on the situation involved and the type of mining being done.
