with the fixed sieve, the jig is suitable for metal ore classification such as placer contained tungsten and gold, tin concentration ore. this jig can be used not only for classification of fine-grained materials but also for that of raw materials with the largest size of 6-8 mm, but in the individual case of placer classification, the largest size is up to 12 mm.
the use of gravity concentration in gold recovery and gold milling flowsheets is well established. in the past, a typical approach was to treat the entire mill discharge with a mineral jig. water, necessary for classification, was added through the jig hutch. jig concentrate was tabled to form a smeltable product.
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.
simple flotation plant with jig to recover metallics in grinding circuit. jig recovers non-floating minerals; unit cell recovers coarse, bulk concentrate, reduces slime losses. small batch cyanidation leaching may be used to obtain all-bullion products. jig removes coarse gold ahead of cyanidation, improves recoveries, eliminates erratic tailings.
next is the separating process, which applies jig roughing and shaking table concentration to remove most of the gangue mineral to obtain gold concentrate. jig is used to process coarse particle, the particle size is bigger than 3mm, while shaking table is used to process fine particle, the particle size that can be recovered is 0.22-2mm.
mineral processing jigs are also known as mineral jigs and if used specifically for gold recovery they are simply called gold mining jigs. our inventory includes jig concentrators with a duplex mineral jig design and centrifugal jig . gold mineral jig concentrator 911metallurgist

jig machine belongs to deep trough separation operations,use water as processing media, jig machine depends on the difference of specific gravity between the mine to be selected and gangue to separate mine, they are mostly in septum type,the stroke and time of stroke is adjustable depend on different specific gravity of mine. 2.gravity separation placer automatic jigging machine jigging machine
savona equipment is one of the leading supplier of jig separators worldwide. mineral processing jigs are also known as mineral jigs and if used specifically for gold
the principle of the alluvial gold mining process is to recover gold and all kinds of associated heavy minerals from raw ore as much as possible by the gravity dressing method. the lower limit of the particle size of gold recovery by gravity separation method is generally 0.01mm. in the practice, the alluvial gold mining process generally includes breaking, screening and gravity separation.

jig concentrator, gold jigs, gold separators, mineral jig . application: it mainly uses for separation alluvial gold, tungsten, tin, diamond, tantalumniobium ore, chrome ore, manganese ore, ilmenite, and some poor ore, such as fluorite, garnet, cinnabar, etc. our jig machine has one or two gear boxes.
the jig screen traps gold nuggets, but the smaller gold falls through the jig screen and to the bottom of the hutch (water tank) to accumulate as a concentrate. the concentrate is bled off continuously through a spigot (‘tap’) in the base of the hutch, as shown below:
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 basic principles are constant: the particles are
0.65 to 90 tph ball mills. ball mill is the key equipment for grinding materials. those grinding mills are widely used in the mining process, and it has a wide range of usage in grinding mineral or material into fine powder, such as gold, iron，zinc ore, copper, etc.
