JT、 跳汰机Gravity Jig

跳汰机选矿是重力选矿的主要方法之一,工艺特点是:被选的矿石连续给到跳汰室的筛板上,形成厚的物料层。通过筛板周期地鼓入上升水流,使床层升起松散,接着水流下降(或停止上升)。在这一过程中,密度不同的颗粒发生相对转移,重矿物进入下层,轻矿物转入上层,分别排出后即得精矿和尾矿。本产品由原地矿部唯一指定企业生产,执行行业标准。

锯齿波跳汰机区别在于:跳汰脉动曲线为锯齿波形,上升水流快而下降水流慢,床层被整体抬起又缓慢下落,有效松散时间长,可大幅度地提高单位筛面的处理能力,降低粒度回收下限,并大量节省筛下补加水。与正弦波跳汰机进行工业试验对比,踞齿波跳汰机回收率提高Sn:3.01%, WO3:5.5%, Pb:1.63%, Zn:2.04%,耗水量减小30-75%。

锯齿波跳汰选矿,除了很微细的物料外,几乎可以处理各种粒度的矿物原料。工艺操作简单,设备处理能力大,并可在一次选别中得到某种最终产品,因此,在生产中应用很广泛。对于金属矿石,是处理粗、中、细粒铁矿锰矿的主要方法之一,并大量用于选别锡、钨矿石;跳汰法在处理含金,钽铌、钛、锆、铬的原生矿石和砂石的选别亦能获得良好效果。

矿石中待分离的矿物密度差越大,入选料度范围越宽,对于含金砂矿,在给料粒度小于25 mm时,可以不分级入选,回收下限可达0.05 mm,对一般金属矿石,实行分级入选,可有效地改善分选指标并提高设备的处理能力。

Oredressing by Gravity Jig is considered as one of the major means for gravity beneficiation with the process characteristics being continued feed of ores to be beneficiated onto screen plate in Jigging Chamber, forming thick material layer. Upward flow is injected via screen plate periodically, allowing the lift of bed layer to be loose and flow to drop(or stop rising ).During this process, grains of different densities will displace relatively, with the heavy materials bring delivered into lower layer and the light material being transferred into the upper layer. Concentrate and tailings will be obtained after their being discharged respectively.

Sawtooth-wave Jig is a new type of energy conservation and highly efficient gravity separation equipment and developed based on the traditional Sine Wave Jig. The difference between Sawtooth .Wave Jig and Sine Wave Jig is that the pulsation curve for jigging is of sawtooth 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 serene surface, decrease of lower limit of grain size recovery and large save of make-up water for undersize fraction. Industrial tests carried out of Sawtooth Wave Jig and Sine Wave Jig for comparison showed that the recovery rate for operation of Sawtooth Wave Jig is raised by Sn:3.01%,Pb:1.63%,Xn:2.04% with water consumption being decreased by 30-75%.

Oredressing by Sawtooth Wave Jig is capable of handling almost full sizes of mineral materials other than very fine material. It features simple process operation, heavy duty equipment handling capacity with final products being obtained through one time separation. Therefore, it has found a wide application in production. It is regarded as one of major means to cope with metallic ores such as iron and manganese ores of coarse, moderate and fine sizes and has found significant use in beneficiating tin and tungsten ores. Moreover, Jigging Method also can achieve a good result in processing primary ores bearing gold, tantalum niobium, titanium, zirconium and chrome and sand stones.

More density minerals to be separated in ores have, wider range the feed sizes have. For gold bearing placer, when feed grain size is less than 25 mm, separation may be carried out without size classification with the lower limit of recovery up to 0.05 mm. For ordinary metallic ores, size classified separation is conducted to effectively improve indexes for separation and to enhance handling capability for the equipment.
