The slag stemmed from copper metallurgy with copper and iron around 0.72% and 39.84% was from Yunye,and was associated gold and silver.Main copper minerals in the slag were elemental copper,chalcocite and zigueline,and iron was mainly in the form of iron silicate.Copper minerals consisted of microgranular disseminated and closed associated with olivine in the slag,which belonged to the refractory secondary copper resource.Concentration process for copper and Ag and Au recovery was determined as stage grinding-stage recovering from the fine particles slag,and mixed middling regrinding with CuSO4 as activator.The laboratory experiment was completed and a mixed concentrate with a Cu grade of 20.27%,Au grade of 2.59 g/t, Ag grade of 230.37 g/t,and Cu recovery of 30.98%,Au recovery of 35.61% and Ag recovery of 34.34% were obtained.These beneficiation indexes were finally improved.
Key words: water-cooled copper slag; CuSO4; activation; regrinding and re-separation; flotation
