To optimize the concentrate grade in the beneficiation process of non-ferrous metals,a fusion algorithm combining fuzzy logic(FL)and immune genetic algorithm(IGA)was developed.Based on this fusion algorithm,a detection model for the beneficiation of non-ferrous metals was constructed to detect and optimize the concentrate grade.Comparative test results show that the data recall rate of the IGA-FL fusion algorithm is 99.7%,with a computation speed of 16.7 bps.The average detection accuracy of the model based on this algorithm is 97.3%,with a detection time of 1.8 s.After applying the detection model based on the IGA-FL fusion algorithm,the concentrate grade of non-ferrous metal beneficiation reached 70.5%,indicating that this model can optimize the concentrate grade effectively.
