| 摘 要： | 选矿的前提是目标矿物和脉石矿物充分解离，因此连生体的比例对选矿指标有重要影响。在不增加投资的情况下，通过流程改造，对工艺流程中的中矿（粗选精矿、扫选精矿）进行再磨，以达到充分解离、降低连生体含量、提高目标矿物可浮性的目的。现场实践表明，经流程改造后，精矿品位由37×10-6提高到45×10-6，金回收率提高了0.6%，每年可产生经济效益1 197.4万元。

| Abstract: | The premise of beneficiation is to completely separate target minerals from gangue minerals,so the proportion of intergrowth minerals has an important influence on the beneficiation indexes.Without increasing investment,it can reach the goals of fully disintegrating,lowing the level of intergrowth and improving the floatability of target minerals by reforming process and regrinding middling （roughing and scavenging concentrates）during the full process.Field practice showed that after process Reformation,the concentrate grade had increased from 37×10-6 to 45×10-6,the god recovery rate was risen by 0.6%,and economic benefits amounted to 11 974 thousand Yuan per year. |
