【Abstract】 The combination of Na₂S₂O₃, Na₂S and NaHS can significantly improve the flotation efficiency of chalcopyrite. In order to scientifically and comprehensively evaluate the comprehensive flotation efficiency of combination adjusters on chalcopyrite, based on experimental data, the factors affecting the flotation efficiency of chalcopyrite were selected to construct an evaluation index system, as well as the maximum deviation method and analytic hierarchy process were used to determine the index weight. Finally, the fuzzy comprehensive evaluation value of flotation efficiency corresponding to different reagent systems for chalcopyrite was calculated by applying comprehensive weights and indicator standard values, thereby obtaining a superior flotation reagent system. The evaluation results show that the combination adjuster system can effectively improve the flotation recovery rate of chalcopyrite, reduce the cost of the agent, and comprehensively improve the economic efficiency of flotation. The research provides certain reference significance for broadening the application of the fuzzy comprehensive evaluation method in the field of mineral processing agents.更多还原
