摘　　要：为了进一步提高江西某铜矿的选矿回收率,在多元素分析和物相分析的基础上,针对该矿石性质及共生嵌布状况,采用条件试验对其药剂制度进行试验,在最佳药剂制度条件下进行中矿再磨新工艺闭路试验研究。结果表明,粗精矿品位达到2.005%,铜回收率达到88.48%,采用中矿再磨新工艺能有效地提高矿石中的选铜回收率。In order to further raise the recovery of a copper ore in Jiangxi, in the light of the ore property and dissemi- nation of symbiosis, a series of reagent system condition test has been completed based on the muttielement analysis and phase analysis. Meanwhile middling regrinding process in closed-circuit test has been explored under optimum reagent sys tern conditions. The results show that the concentrate grade of copper is 2. 005% and recovery of copper is 88. 48% with reasonable reagent system. The result of flotation test indicates that middling regrinding new process is beneficial to rai- sing recovery of copper.
