论脉金矿选矿厂在磨矿回路中加重选作业回收金的效果

Effectiveness of addition of gravity separation in grinding circuit of vein gold concentrator for increasing gold recovery

分析了在脉金矿选厂的磨矿回路中增加重选作业的优越性和可行性，并作了实例介绍。该法可预先回收已单体解离的粗颗粒金，有利于提高金的回收率，减少尾矿中金的损失、且设备简单、投资少、成本低。

The advantages and feasibility of adding the gravity separation in the grinding circuit of vein gold concentrator were analyzed with case description.Through prerecovery the liberated coarse gold grains,this processing method enables to increase the gold recovery and to reduce the gold loss in tailings with simple equipment,low capital investment and low processing costs as well as less environment pollution.
