摘　　要：运用灰色关联分析法对离心复合力场回收废弃电路板金属过程中反冲水、转速和浓度等操作参数对分选效果(精矿品位和精矿的回收率)的影响进行了研究,获得了影响因素的显著性序次:反冲水>转速>浓度。This paper studied the influences of recoil water pressure, rotation speed and slurry con- centration to the separation effect （grade and recovery of concentrates） in metals reclamation from discarded printed circuit boards by enhanced centrifugal separation. The influential order of the pa- rameters was obtained and described as recoil water pressure 〉 rotation speed 〉 slurry concentration.

关 键 词：离心分选 精矿品位 回收率 灰色关联分析
