摘要: 某选厂选矿工艺流程为重选-浮选-重选。重选预选现场采用φ2 000 mm螺旋溜槽和螺旋分级机分级联合丟尾,抛尾率佷低,螺旋溜槽分选后的尾矿含锡高,锡金属损失率大。鉴于此,提出采用锯齿波跳汰机取代螺旋溜槽分选双螺旋返砂。实验室小型试验跳汰尾矿含锡、铅、锌品位为0.08%、0.07%、0.38%,抛尾率达到55.52%;跳汰精矿的金属回收率分别达到90.67%、86.50%和89.26%。现场工业试验当给矿含锡0.61%,抛尾产率为54.13%,锡、铅、锌金属回收率分别达到91.22%、87.10%、和80.35%;当给矿含锡0.81%,抛尾产率为43.51%,锡、铅、锌金属回收率分别达到95.45%、91.12%、和88.79%。

Abstract: A mineral processing plant adopted a beneficiation process of gravity separation-flotation- gravity separation.Its gravity separation for pretreatment using a combination of φ2000 mm spiral sluice and spiral classifier to discard tailings had a very low tailing discard rate and the tailing of the spiral sluice had a high tin content, leading to a great loss of tin metal.Therefore, it was proposed to use a sawtooth wave jigger to replace the spiral sluice for treating the circulating load of duplex spiral classifier.The laboratory test produced a jigger tailing containing 0.08% Sn, 0.07% Pb and 0.38% Zn, with the tailing discard rate reaching 55.52%.The metal recoveries of the jigger concentrate were 90.67% Sn, 86.50% Pb and 89.26% Zn.The industrial test achieved metal recoveries of 91.22% Sn, 87.10% Pb and 80.35% Zn from a feed assaying 0.61% Sn at a tailing discard rate of 54.13%.When the feed contained 0.81% Sn, the metal recoveries were 95.45%Sn, 91.12% Pb and 88.79% at a tailing discard rate of 43.51%.
