Abstract

Abstract:

A beneficiation test of a sulfide-oxidized copper ore from Guizhou was studied. Ore milling grade is Cu:1. 27%，Ag:3. 80g/t，As 4. 46g/t and the oxidation rate of copper is 23. 87%. It belongs to the mixed copper. According to the ore properties，a comparative test was performed on the three kinds of copper extraction processes, which are oxygen sulfur mixture，oxygen sulfur separation and flotation tailings acid leaching. The results show that copper concentrate grade of 20.52% and recovery of 73.05%; copper grade of 880.00 mg/L, leaching rate of 14.16% in medium and the total recovery of 87.21% was achieved through the whole closed trial, which was flotation，tailings acid leaching.

Key words: sulfide-oxidized copper, flotation, leach
