摘要
为了提高米拉多(Mirador)铜矿的总铜回收率,针对现场粗选尾矿中+75 μm粒级铜品位较高、铜损失率大的问题,采用新型Hydrofloat水力浮选机试验,考察了水力浮选机充气量、上升水流量、捕收剂丁基黄药用量和起泡剂F-501用量等因素对粗选尾矿预富集效果的影响.结果表明:在充气量为0.85 m3/min,上升水流量为5 L/min,丁基黄药用量为20 g/t,F-501用量为20 g/t的情况下进行浮选,可获得铜品位0.30%、回收率86.7%的粗精矿.试验结果可以为现场流程改造提供参考.
Abstract
In order to improve the total copper recovery rate of Mirador copper mine,aiming at the problems of high copper grade and large copper loss rate in the+75 μm fraction of roughing tailings,a new Hydrofloat hydraulic flotation machine was used to investigate the effects of aeration rate of hydraulic flota-tion machine,rising water flow rate,collector butyl xanthate dosage and foaming agent F-501 dosage on the pre-enrichment effect of roughing tailings.The results show that flotation experiment carried out when aera-tion rate is 0.85 m3/min,rising water flow rate is 5 L/min,butyl xanthate dosage is 20 g/t,and F-501 dos-age is 20 g/t,the rough concentrate with copper grade of 0.30%and recovery rate of 86.7%can be ob-tained,which can provide reference for on-site process transformation.
