For scheelite ore, floatation separation is mainly used while gravity separation is involved sometimes. For wolframite, gravity separation is mainly used while magnetic separation can be involved sometimes. However, there are also exceptions. For some scheelite tungsten ore with coarse inlay granules, gravity separation can help to get the ideal upgrading efficiency without large investment about floatation separation plants. And if floatation separation is used for this scheelite, the recovery of high-quality scheelite will be lower and the plant investment will be large. In Africa, there are many scheelite tungsten mines with big coarse scheelite inlay size even over 5mm, and here the gravity separation can be used to recover the coarse scheelite and this lowers the schelite loss due to crushing or milling. If floatation separation is used for this coarse scheelite ore, the recovery will be lowered and this will be not so good as gravity separation. Here the scheelite tungsten gravity separator is tungsten jig separator.
Illustration:
Saw-tooth-wave jigger of JT5-2 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:
JT5-2 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
