Abstract

Abstract

The gold-bearing copper ore contains 0.85% copper and 0.90 g/t gold, and the oxidation rate of copper is 21.17%.In order to develop and utilize the gold-bearing copper ore, the process mineralogy was carried out. The synchronous flotation technology of sulfide minerals and oxidized minerals was developed to realize the comprehensive recovery of copper and gold. The results showed that the copper-gold concentrate with copper grade of 15.36% and gold content of 12.58 g/t was obtained by the closed-circuit recycling process of one roughing, three scavengings, and three cleanings. The recovery of copper and gold was 70.93% and 54.33%, respectively.
