During the operation of metallurgical plants, a large amount of waste is generated. Pavlodar aluminium plant has three sludge collectors, two of which have already been taken out of service due to filling. A large amount of bauxite sludge containing many valuable elements such as aluminium, copper, iron, manganese, chromium, and titanium is stored in these sludge collectors. For their utilization and prediction of the distribution of the concentrations of elements, it is required to make a qualitative and quantitative assessment of the composition of the waste. For this purpose, on the territory of the third (exploited) sludge collector samples were taken, indicating the coordinates of the sampling site on the map. The samples were analyzed on a BRA-18 X-ray fluorescence analyser. The concentration of elements was estimated using the artificial neural network (ANN). A separate neural network was created for all analyzed elements. The Levenberg-Marquardt algorithm was used for training. Based on the results of the ANN tests, graphs of the concentration of aluminium and copper were plotted depending on the place of sampling. As a result of the experiments, it was noted that the true concentrations of the analyzed samples for aluminium and copper are in good agreement with the predicted concentrations for these elements.
