There is big differences of density, color, metal lustre between stibnite and its inlayed gangue, so most stibnite antimony can be upgraded by gravity separation with its low plant investment and friendly to environment. The handling size range of gravity sepatator can be wide and this gravity separation can be also the preparation of further flowtation separation if floatation separation is needed. 

There are many different kinds of gravity separation machines during which the stibnite jigging machine is the most economic and most efficient antimony beneficiating equipment. This kind of antimony upgrading jigger is friendly to environment with its high recovery rate, great beneficiating efficiency, large handling capacity, and small plant investment. Forui has been in manufacturing and researching and designing jiggers for 25 years and has enlarged the feeding size range and large water consumption. There are 7 series of jiggers suitable for many different mineral separation with the feeding size range of 0-50mm. 

Forui is a professional jigging machine manufacturer of kinds models. Small test can be done for you free if samples about 15kgs can be available.

Saw-tooth-Wave Jigger

Illustration:
Saw-tooth-wave jigger of JT series is driven by saw-tooth wave and works by rising up and down water-stream
uniformity & serrated. It works greatly for ore/slag material of thin granularity size. It is widely used
in beneficiation of kinds of metal & non-metals & smelting slag like tungsten, tin, gold, iron, manganese, titanium,chromium, sulfur, silica-manganese slag, ferro-manganese slag, ferro-nickel slag etc. 

Working Principle:
JT jigger is kind of down-moving saw-tooth-wave jigger. Magnetic reduce motor drives the saw-tooth-wave producer to make different-heart movement through the cam. And the adjustment device will be driven to do alternate motion to make hypocentrum produce the regulation motion to squeeze the water in box move. The water-flow moving goes through the screen to dash the bed stones and the ore to move along parabola. Then the ore will be fed at the feeding port. The dropping speed differs for materials with different density to form different layers naturally.The light material will be discharged by the dashing of water while the heavy material will go down through the bed stones to the hypocentrum. Finally, the concentrate will be discharged to finish the jigging.
 
Merits:
1) water-recycling & low power
2) semi-automatic & easy to operate
3) continuous working & environment-friendly
4) quality & service-guaranteed
5) seaworthy & durable
