Abstract

This study focuses on the results of monitoring of changes in natural resource components in the steppe zone of the Southern Ural region under conditions of technogenic impact of copper ore extraction and processing using Earth remote sensing data. Landsat satellite images received in 2014 and 2023 have been comprehensively analyzed. The application of vegetation indices, in particular, the NDVI index, has revealed a decline in vegetation levels around the mining and processing plant over the study period. Further analysis using the ferrous minerals ratio index and “false color” method has confirmed the expansion of areas occupied by waste dumps and tailings, as well as an increased iron concentration in the soil. Chemical analyses have confirmed the presence of elevated metal concentrations at the tailings storage facility. The findings highlight the impact of the mining and processing plant on the environment and emphasize the need for systematic monitoring of the situation.
