【Abstract】 A sigmoidal backpropagation neural network model for high gradient magnetic separation was developed in this paper. The performances of various network models with different numbers of hidden nodes were evaluated. The application of the sigmoidal backpropagation neural network model to the simulation of high gradient magnetic separation processes of chalcopyrite was illustrated. The simulation results show that the model is capable of making a good prediction over a broad range of operating conditions and the developed model is reasonable and feasible.更多还原
