重力选矿是砂金的主要选别方法,重选设备品种及规格繁多,正确选用重选设备是决定选别作业成败的关键.本文拟对主要黄金重选设备作一简介,以供参考.一、跳汰机主要有侧动隔膜的尤巴型、下动隔膜的泛美型、旁动隔膜的丹佛型及圆形跳汰机.圆形跳汰机的特点是矿浆沿径向流动,脉动曲线为锯齿状,可节约用水,提高细粒金的回收率.工业试验表明,它可回收74微米以至40微米的黄金.
Gravity beneficiation is the main sorting method of the gold, reselection of equipment variety and variety of specifications, the correct selection of re-election equipment is the key to determine the success or failure of sorting operations.This paper intends to make a brief introduction of the main gold re-election equipment for reference.A, Jig mainly Yuba type side diaphragm, pan diaphragm under the Pan American, Denver and circular jig next to the diaphragm. Circular jig is characterized by radial flow along the pulp, pulsation curve As serrated, water can be saved and the recovery of fine gold increased.Industrial tests show that it can recover gold from 74 microns to 40 microns.
