摘　　要：根据国内某钨矿光电拣选工业试验,对光电拣选原矿给料粒度、抛废率及设备处理能力进行了系统性分析研究,该钨矿在原矿拣选入料品位0.22%,入料粒度10~40 mm的情况下,采用K-108光电拣选设备,可获得钨品位0.26%的钨精矿,拣选尾矿钨品位为0.046%,拣选抛废率21.84%,拣选精矿钨金属回收率95.38%,光电拣选工艺对该钨矿有明显分选效果。研究发现分析矿取样不规范是造成工业试验抛废精矿回收率过高的根本原因,拣选循环负荷量是影响拣选工艺稳定性的关键因素。Based on an industrial experiment at a domestic tungsten mine,a systematic analysis was conducted on the ore feed size,reject rate,and equipment processing capacity in the photoelectric sorting process.With an original ore grade of 0.22%and an ore feed size of 10~40 mm,the use of the K-108 photoelectric sorting equipment yielded a tungsten concentrate with a grade of 0.26%,a reject tailings tungsten grade of 0.046%,a reject rate of 21.84%,and a tungsten metal recovery rate of 95.38%.The photoelectric sorting process showed a significant separation effect for this tungsten mine.The study identified that non-standard ore sampling was the fundamental reason for the high reject and concentrate recovery rates in the industrial test,and the sorting cycle load was a key factor affecting the stability of the sorting process.
