Conclusions
-
A novel accurate, efficient and stable computational method, known within the literature as the splitting method, has been applied to describe the heterogeneous comminution behavior of the multicomponent-component mineral system. The splitting method removes the mathematical flaw present in the decomposition method previously published (Mehta, Adel and Yoon, 1989, 1990). Having been demonstrated to work in all cases, the splitting method provides as accurate a solution as the analytical method.
-
The splitting method has been demonstrated to be efficient because the model fits the experimental data much better than the fitting obtained by the decomposition method.
-
The splitting method, in conjunction with the parameter estimation scheme, yields a convergence of the parameters irrespective of the magnitude of the initial change. Thus the method’s stability is demonstrated.
