| Résumé : | In this paper, a comprehensive approach for modelling, parameter estimation and globalsimulation of the grinding circuit of the Kolwezi Concentrator is presented. This process can be describedby a nonlinear distributed parameter system. To differentiate between wet and dry grinding, the derivedmodel takes into account the increase of the specific rate of breakage in the wet grinding process. In orderto determine material transport dynamics within the mills, a new experimental method has beendeveloped. Due to the lack of a colorant or a radioactive sensor, this procedure is based on the use of theG41 foaming as tracer. Both steady-state and dynamic simulation results are discussed and are shown tobe in agreement with the experimental data. |
