Novel computational approach toward the mill matrix of distributed comminution models

This note presents the correct solution method for solving the general model equations of a multicomponent mineral system containing multiple classes of locked particles. A novel accurate, efficient and stable computational method known as the splitting method was applied to describe the heterogeneous comminution behavior of the multicomponent mineral system. The splitting method fits the experimental data better than the decomposition method. Also, in conjunction with the parameter estimation scheme it yields a convergence of the parameters irrespective of the magnitude of the initial change, demonstrating the method's stability.
