Abstract
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. .
Highlights
The purpose of each investigation, which is the scientific cognition of the reality, is based on the aspiration to determine the facts characterizing referred object, the process or the aspect
Copper extraction from the flotation waste, disposed as the byproduct of the Bor Copper Mine (Serbia), was used as one example of the industrial process whose technological and ecological parameters were the subject of optimization
Using the final model equation (Equation 7), which predicts the real output of the investigated system accurately enough (R2 = 0.634), it is possible to determine optimal conditionс for operations management of the copper extraction process
Summary
The purpose of each investigation, which is the scientific cognition of the reality, is based on the aspiration to determine the facts characterizing referred object, the process or the aspect. It is obvious that the first stage in such efforts is data collection by observing or measurement, which is the starting point toward determination of the model, that has to assert the information about the object, included in the results of the observations. This can be explained by the fact that each separate result of observing the same system has, more or less, similar character (yet not identical).
