description: The purpose of the work: based on the analysis of industrial data of the Kandalaksha aluminum plant for 2001-2021, to identify patterns (lack of patterns) of the influence of the conditions of the industrial electrolysis process on the consumption of raw materials in the production of metallurgical aluminum for the above period. Theoretical aspects of electrolytic aluminum production are considered. Methods of analysis of alumina and fluorosol consumption in the aluminum industry have been studied. The assessment of the raw materials used at KAZ, the method of its storage and transportation, methods of quality control, accounting and flow control was carried out. It was found that an increase in the moisture content in alumina by 0.1% by weight increases the specific consumption of aluminum fluoride by about 0.134 kg/t. An increase in the duration of the anode effect by one minute increases the consumption of aluminum fluoride by 1,768 kg/t. No factors significantly affecting the consumption of the anode mass were identified in the framework of this work. Measures are proposed to reduce the consumption of raw materials during the industrial electrolysis process in the production of metallurgical aluminum on KAZÐµ.
