Gravity Separation Diaphragm Jig Gold Jig Concentrator Copper Jigger Machine

Jig machine separation belongs to deep groove sorting operation in ore dressing work. It adopts water as beneficiation medium, separates the minerals by use of gravity differences between the mineral ore and gangue.

Jig machine is widely used in manganese ore, Lead-zinc mine, lapis lazuli, barite ore, fluorite, pyrite, limonite, hematite, mercury and other minerals re-election. jig machine is applied to the separation operation. It has a good effect on the separate of big size raw ore and the recovery of large non-ferrous metal smelting slag.

Working Principle

Jigger machine beneficiation is one way of gravity beneficiation. It belongs to deep trough separation operations, use water as processing media, it depends on the difference of specific gravity between the mine to be select 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, it’s widely used to select Tungsten, tin, gold, red iron, brown iron, manganese, titanium, antimony, lead, tantalum, niobium and other metal.

(1) The ore particles are mainly layered by specific gravity in the jig. The jig can not only sort the narrow grade of ore, but also effectively sort the wide and non-graded ore.

(2) In the jigging process, the higher the specific gravity of the medium, the greater the difference in specific gravity between the ore particles, the higher the sorting efficiency.

(3) Maintaining the bed with the necessary looseness is a prerequisite for stratification. If the bed is not loose enough, the ore particles are difficult to transfer to each other and thus the possibility of delamination is lost. Therefore, in the jigging process, the bed is in a loose state as much as possible to improve the processing capacity of the jig and improve the sorting effect.

(4) The influence of the size and shape of the ore particles on the stratification mainly occurs during the period of relative movement between the ore particles and the medium. Therefore, when sorting non-grading materials, the period of relatively large moving speed should be shortened as much as possible during the jigging period and the period of relative motion speed should be extended to keep the bed tight.

(5) The rising water flow should have a large positive acceleration and a small negative acceleration; the descending water flow should have a small positive acceleration and a large negative acceleration.

(6) The inhalation effect of the descending water flow is an aspect of the jigging layer, which can improve the jigging effect of the narrow-level and non-graded ore particles, but the strength and duration of the inhalation action should be selected according to the nature of the raw material.

(7) When hopping fine-grained ore, increasing the frequency of water flow movement in the jig can improve the sorting effect.

(8) Adding some high-specific gravity fine ore particles to the bed layer can improve the jigging effect of the non-classified ore, but the jig must be re-adjusted to enhance the inhalation.
