| Abstract: |
| Because heap leaching is a complicated process and has a lot of uncertain factors,using a grey-system-theory-based approach for predicting the leaching rate of heap leaching is studied.According to leaching dynamic characteristics of heap leaching and by use of a practical example,a model of GM(1,1) of equal dimension grey data is established for predicting the leaching rate of heap leaching.The prediction results show that the approach is reasonable and reliable,and in good agreement with field measurements with the greatest relative error of only 2.5%. |
