Abstract: Five different kinds of flotation processes were proposed based on preliminary research on a difficult copper oxide copper mine in sichuan province.The choice of flotation process requires a comprehensive consideration of recovery,grade and yield,which are difficult to identify accurately.In this context,the analytic hierarchy process (AHP) is used for the evaluation of mineral selection index,and the quantifiable evaluation index is obtained to determine the optimal flotation process.Using analytic hierarchy process (AHP) concentrate and tailings of hierarchical analysis model is set up respectively,quantitative determination of recovery,grade and yield were analyzed,and the weights of the final comprehensive total target sequence analysis and evaluation.Research results show that the concentrate and tailings model under the condition of the preferred recovery or grade,all choose process five as the best flotation process,and combining with the experience to judge the results,verify the feasibility of analytic hierarchy process (AHP) is used in ore dressing process decision-making,enhance the accuracy of decision.
