振动离心选金机在某金矿的应用试验

Application experiment on vibration centrifuge for gold selecting in a gold mine

振动离心选金机是一种高速旋转、高频振动的离心式重选设备,具有富集比高,功率低等特点,在某金矿对磨机排矿、浓密机底流等进行选金试验,取得较好效果。处理浸前浓密机底流,间隔时间2～4h,精矿品位300g/t,回收率12%～19%左右;处理一段分级机溢流,间隔时间2～4h,精矿品位300g/t以上,回收率22%～30%。

Vibration centrifuge for gold selecting is a high rotating speed,high-frequency vibration gravity concentration equipment.Its enrichment ratio is high while the power consumption is low.It is used in gold seperation experiments for ball mill discharge and thickener underflow,in which good effects are obtained.For thickener underflow whose gold grade is 300 g/t,the recovery ratio is 12%～19%for 2～4 hours interval.For first stage classifier overflow whose gold grade is more than 300 g/t,the recovery ratio is 22%～30%for 2～4 hours interval.The equipment is of high popularization value.
