摘要:This paper presents the modeling procedure of one real technological system. In this study, the copper extraction from the copper flotation waste generated at the Bor Copper Mine (Serbia), were the object of modeling. Sufficient data base for statistical modeling was constructed using the orthogonal factorial design of the experiments. Mathematical model of investigated system was developed using the combination of linear and multiple linear statistical analysis approach. The purpose of such a model is obtaining optimal states of the system that enable efficient operations management. Besides technological and economical, ecological parameters of the process were considered as crucial input variables.
