Mineral Processing Research for an Low Grade and Ultra-fine-grained Dissemination Mixed Copper Ore

As the ore is insufficient oxidation,a series of altered copper minerals were formed.It is an incomplete oxidation,low grade and ultra-fine-grained dissemination mixed copper ore with the oxidation rate 45.45% and the copper grade 0.77%.According to the characteristics of the ore,mineral processing researches were carried on.With the technical flowsheet of triple roughing,once scavenging and twice cleaning,copper concentrate of 24.57% copper with a recovery of 84.14% was obtained.The technological process and reagent system are simple and easy to realize commercial production.
