Abstract

Abstract

The method of developing GM(1,1) model is extended on the basis of grey system theory.Some conditions of the transfer function,which not only improve the smooth degree of original data sequence but also decrease the revert error,were given.The grey dynamic model was first combined with the transfer function to predict the leaching rate in heap leaching process.The results show that high accuracy of prediction can be expected by the method used.This provides a new approach to realize the prediction and control of the future behavior of leaching kinetics.
