摘　　要：某铜矿石含铜0．84％，铜氧化率15．30％，含铁23．12％，铜铁矿物嵌布紧密，单体解离困难．当磨矿细度为-0．074mm92．55％时，铜的单体解离度为86％．针对该矿石特性。铜粗选采用选择性好、捕收能力强的DY-1作捕收剂，再磨中添加石灰，铜精选分离中采用调整剂TZ，取得铜精矿品位21．54％，回收率66．67％的选矿技术指标，为该铜矿的开发提供了可行的技术依据．A Cu-S ore assays 0.84% Cu, 15.30% of copper oxidation rate and 23.12% Fe. Primarily finegrained dissemination occurred in the minertals of copper and iron. When head ore is ground to 92. 55% -0. 074 mm, the literation degree of copper minerals is 86%. According to characteristics of the ore, the newly-type collector DY-1 with excellent selectivity and collecting was selected in the process of copper roughing, quicklime was used to the second grinding and Modifier TZ was devoted to copper concentration. Satisfactory separation result is obtained. The copper concentrate contains 20. 54% Cu, the copper recovery is 63.88%, which provided viable technical basis for the development of this kind of ore and the similar-type complex ore.
