“…As a result of the study of a considerable number of literature sources and, accordingly, ideas that were proposed to simplify the development of a mathematical model, it can be concluded that not many of the previously considered options present the apparatus under study in the form of such a mathematical model that would clearly display what happens in the electrolyser during the process of aluminium production. The existing models describe the change in various parameters of the electrolyser in time: a partial differential equation, for example, such as the supply voltage of the electrolysis bath or the amount of metal poured out of the electrolyser [8,9]. However, to understand this model, it is still necessary to understand the basis, e.g., what each variable means, how the constant coefficients are determined, etc.…”

The technological process of aluminium electrolysis is a complex scientific and technical task. This is due to a large number of internal, external and resultant factors. The aim of this work is to analyse these factors, assess them and their influence on the technological process of electrolysis and develop a comprehensive and mathematical model of aluminium production in the Soderberg electrolyser. The work analyses the technological process of primary aluminium production on the basis of the Bayer method and then on the basis of the Hall–Eru method. The existing methods and technologies for computer modelling of the technological process are analysed. The modern methods of analysis for thermal and electromagnetic fields in electrolysers are considered. On the basis of an in-depth analysis, a number of factors influencing the process of primary aluminium production are identified. Using the methods of system analysis to analyse the identified factors, a ranked list of factors according to the degree of influence is obtained. Using the Pareto diagram, we obtain a list of factors with maximum impact. A conceptual model of the technological process is derived. Based on the obtained conceptual model, the mathematical model of the technological process is derived. The conducted research may be useful to specialists in the field of metallurgy for the analysis of the technological processes of primary aluminium production.
