摘要:
福建某铜金矿为典型的含铜金多金属硫化矿，矿石中可综合回收的主要有价元素为金、银、铜、硫。针对该矿石性质，进行了混合浮选—粗精矿再磨—铜硫分离工艺研究，考察了磨矿细度、抑制剂、捕收剂等因素对浮选指标的影响。结果表明：在最佳试验条件下，闭路试验获得的铜精矿铜品位23.61 %、金品位185.00 g/t，铜、金回收率分别为95.77 %、85.86 %；?蚓笸肺唤鑫0.03 %、金品位3.30 g/t，铜、金回收率分别为0.47 %、5.97 %。研究结果对该矿石中铜、金的回收利用及工业生产起到了指导作用。

Abstract:
A copper-gold ore in Fujian is a typical copper-gold polymetallic sulfide ore.The useful minerals that can be recovered comprehensively are mainly gold,silver,copper and sulfur.Based on the ore property,the paper conducts the study of mixed flotation-coarse concentrate regrinding-copper and sulfur separation process and investigates the influence of grinding fineness,inhibitor and collector on flotation indexes.The results show that the closed-circuit test obtain the copper concentrate with copper grade 23.61 % and gold grade 185.00 g/t,and the recovery rates of copper and gold are 95.77 % and 85.86 % respectively;the sulfur concentrate contains 0.03 % copper and 3.30 g/t gold,and the recovery rates of copper and gold are 0.47 % and 5.97 % respectively.The study results play a guiding role in the recycling and industrial production of copper and gold in the ore.
