摘　　要：采用机械力化学方法活化铜精矿,试验条件为球料比20:1,矿浆浓度25%,球磨机转速240r/min。通过粒度测试、密度测定、XRD、SEM、TG-DTA等一系列分析表征后发现:铜精矿经球磨之后,其粒度大小、晶体结构发生了变化,由晶型向无定形转化,铜精矿的活性被激发出来。Copper concentrate was activated by a mechano-chemical method. Through a series of analyses and tests including panicle size test, density test, XRD, SEM and TG-DTA, it is found that after the activation, the particle size was reduced and the crystalline structure has changed into amorphous structure.
