摘　　要：浮选中矿的一次精选尾矿和三次扫选的泡沫产品经旋流器分级后,底流返回球磨机再磨,使金铜矿物的连生体进一步单体解离,提高了选矿回收率;改善了一次精选及扫选的作业环境,提高了精矿质量。A research on middling regrinding was carried out in Shuguang gold copper ore - dressing plant. The tailings of once cleaning separation and the foam products of thrice sort separation were pump into cyclone, and the overflow materials were returned to the ball mill. Then, the association particles of gold-copper materials can be disassociated further. As a result, the ore dressing recovery percentage and quality of concentrate was enhanced.
