摘　　要：通过自动矿物特征分析系统(AMICS)分析、重选试验、磁选试验以及电选试验,研究了如何降低难选锆中矿中杂质矿物,提高锆英砂品质和回收率.结果表明:通过“重选—磁选—电选”联合工艺,获得ZrO_(2)品位和回收率分别为65.58%,59.5%的锆精矿和ZrO_(2)品位和回收率分别为61.64%,18.66%的锆次精矿,精矿合计回收率为78.16%,取得了较好的选别指标.The methods of reducing impurity minerals of a low grade zirconite ore and improving the quality and recovery rate of zircon sand were studied by using the automatic mineral characteristic analysis system,gravity separation test,magnetic separation test and electric separation test.The results show that through the combined process of gravity separation,magnetic separation and electrical separation,the zirconite concentrate product has a ZrO_(2) grade of 65.58%and a recovery rate of 59.5%;and the zirconium secondary concentrate product has a ZrO_(2) grade of 61.64%and a recovery rate of 18.66%.The total recovery rate is 78.16%,which demostrates that high separating index can be achieved.
