Descriptions of Coarse Scheelite Tungsten Ore Processing Plant in Africa-II

However, there are many scheelite tungsten mines with big coarse scheelite inlay size even over 5mm in Africa, and here gravity separation can be used to recover the coarse scheelite granules and this lowers the scheelite loss due to crushing or milling. If floatation separation is used directly for this coarse scheelite ore, the recovery rate will be lowered and this will be not so good as gravity separation. Here the scheelite tungsten gravity separator is scheelite jig separator. Gravity separation of jigging separator-shaking table is very common to use in the real operation.

Well tech company Saw-tooth Wave Jig is a new type of energy saving and high efficient gravity separation equipment and developed based on the traditional Sine Wave Jig. The difference between Saw-tooth Wave Jig and Sine Wave Jig is that the pulsation curve for jigging is saw-tooth wave shape, with speedy upward flow and slow downward flow. Bed layer is elevated integrally and slowly dropped with a long effective loose time, allowing significant increase of handling capacity for unit screen surface, decrease of lower limit of grain size recovery and large save of make-up water for under size fraction.

In practice, contrast of Saw-tooth Wave Jig and Sine Wave Jig shows up raises of recovery of Saw-tooth Wave Jig: Sn:3.01%, W:5.5%, Pb:1.63%, Zn:2.04%.
