1.Introduction of Gemstone Processing Machine
The Gemstone Processing Machine is a simple gravity separation metallurgy machine as it's essentially an open tank filled with water with a slightly inclined screen at the top and provided with a spigot on the underside for drawing off the concentrate. 

Rectangular gold jigs are made of either a single 1 jig-cell as stand-alone, or a series of cells organized in modules of two, three or four cells. The popular one is 2 cells.

In a multiple-cell jig design/setup, the rejected tailings from the front cell passes thru as feed to the following second cell compartment. Tailing from the second cell vessel is feed to the 3rd cell and on down the bank.

Ordinarily, roughing duty is done using three or four cell modules. The double or two-cell arrangement that is commonly called the duplex is ordinarily confined to secondary circuits and cleaning systems.

Gemstone Processing Machine belongs to gravity-based equipments, which can separate mineral based on different specific gravity. saw-tooth wave jig is mainly consist of tyhree parts: main frame, driving set and jigging chamber. Jigging machine is widely used in gravity concentration og gold, diamond, tin, barite, tungten, placer gold, hematite ore, manganese, titanium, antimony, lead, tantalum, niobium and other minerals.



2.Details of Gemstone Processing Machine

The mineral bed is repeatedly moved up by the water, expands, and then re-settles. The resettlement occurring with the water flowing down at a lower rate.
The practical importance of jigging is that stratification occurs with the denser minerals at the bottom of the bed and the lighter minerals at the top .

3. working principle and structure of Gemstone Processing Machine

Gemstone Processing Machine for cassiterite need water to work, and it loosens materials in vertical alternative water-flows, and it forms different layers of materials of different densities and discharges both layers from up and down discharging ports separately.

    The basic composition of jigger is jigging chambers, also called jigging boxes, and there are screens in each chamber. Water and raw ore will be fed from one end of the jigger screen, the ore granules will move in the vertical alternative water-flows. Layers will be formed because of density difference of materials. The minerals with small density will be in the up layer and will flow together with the up pulp flow while material with bigger density will be in the down layer and will discharged from the down discharging port as jigging concentrate.
