Abstract:In this study, the current beneficiationprocess of the copper polymetallic orein Tibet was investigated systematically. Based onmineralogical analysis of the raw ore,the key factors affecting the quality of copper concentrateproduct were identified through theoptimization tests of flotation, and a new reasonable technological process was designed and proposed in this paper. The results indicate that a better copper concentrate product with the grade of copper is increased to20.66% and recovery of copper is increased to79.81% after the optimization of process parameters. The flotation tailings contain 0.21% copperwhich mainly exists inthe oxide copper minerals.
