Abstract
A Cu-S ore assays 0.84% Cu,15.30% of copper oxidation rate and 23.12% Fe.Primarily fine-grained dissemination occurred in the minertals of copper and iron.When head ore is ground to 92.55%-0.074 mm,the literation degree of copper minerals is 86%.According to characteristics of the ore,the newly-type collector DY-1 with excellent selectivity and collecting was selected in the process of copper roughing,quicklime was used to the second grinding and Modifier TZ was devoted to copper concentration.Satisfactory separation result is obtained.The copper concentrate contains 20.54% Cu,the copper recovery is 63.88%,which provided viable technical basis for the development of this kind of ore and the similar-type complex ore.
