In continuous process industries, large investments in automated process control systems are made to reduce variance, but the variance in key process parameters often remain unchanged. One reason is that the operators often lack tools to assess the impact of process changes on the final product properties. Dynamic simulation could be used to estimate effects of attempted changes, on models with current process information and dynamics. However, the use of dynamic simulation for such purposes is infrequent in process industry. Therefore, the purpose of this paper is to outline a simulation model for mineral processing using existing process knowledge. An iron ore pelletizing process was studied, and process knowledge was collected through interviews and research reports. The material flow mechanisms of a critical process section were also determined experimentally. A simulation model of the process was constructed in SIMULINK, and the effects of various variations were tested. The statistical properties of the output distribution of particle residence times were compared for various settings. Finally, various applications field in a mineral process for the simulation model is discussed, for example, predicting or explaining effect of corrective actions.
