The relevance of the research is caused by the acquisition of new knowledge on optimization of the technological parameters of centrifugal concentrator operation using the Knelson CVD technology, namely: setting the frequency of opening the valves and the time during which the valves remain open. The aim of the research is a statistical analysis of the results of semi-industrial studies of the Knelson CVD technology applicability on various products of the factory, using the method of group accounting of arguments, to derive dependencies between the concentrate yield and tunable parameters, which allow preliminary calculations of the effectiveness of implementation of this technology at the processing enterprises. Objects: products obtained as a result of hydrocyclone operation, as well as the technological parameters of the centrifugal concentrators. Methods: general methods of mathematical statistics, in particular, regression analysis methods aimed at constructing statistically significant models describing the dependence of a variable on the set of regressors. Also, along with the classical apparatus of regression analysis, the method of group accounting of arguments was used. The main idea of ​​the method is to build a set of models of a given class, and to select optimal one among them. Results. The authors have developed the effective method for processing the results of tests carried out on the processing equipment, based on the method of group accounting of arguments. Based on the obtained data, statistically significant models were constructed, describing the dependence of the content in tails and the concentrate on valuable components on various adjustable equipment parameters, and their effectiveness was justified, which makes it possible to apply these models in further studies on the application of CVD technology. The paper demonstrates the application of the method of group accounting of arguments using the example of constructing polynomial regression models containing non-linear combinations of regressors.
