In order to accurately simulate the variation process of gold leaching rate, a multistage leaching model was designed, and the reaction rate prediction model based on the Forward Neural Network (FNN) and Radial Basis Function (RBF) was constructed.The validity of the model was verified by numerical simulation and comparative test. The results show that the error between the predicted value and the actual value of the gold leaching rate is between 2.1% and 2.6%, which is effective and accurate.
