| 摘 要： | 针对某铜选厂浮选工艺流程,采用中矿再磨工艺进行选矿试验,对比了不同中矿再磨钢球配比条件下的选矿效果。不同钢球配比条件下,新工艺的回收率不同,说明中矿再磨不同球比磨矿的针对性不同。运用筛析法、点测法对中矿磨前、磨后颗粒进行了分析,发现中矿磨后能有效的降低粗颗粒粒级的数量,解离度增加,中间粒级及细颗粒级产率增加。对新工艺的机理进行了分析。

| Abstract: | Based on the investigation of flotation process in a copper mineral processing plant,experiment of adding regrinding of middling to the old mineral processing flow was carried out,the flotating results for regrinding of middling under different filling ratios of steel ball were compared.For new mineral processing flow,when the steel ball ratio was different the recovery of copper was different also,this indicated that regrinding of middling with different steel ball ratios was of different pertinency.The pa... |
