This investigation was conducted using waste rock materials from the Ak-Sug porphyry Cu-Mo deposit, which is located in the northeastern region of the Tuva republic in Russia. To predict the formation of acid mine drainage, the waste rocks were investigated using X-ray fluorescence with synchrotron radiation spectroscopy (XRF-SR), X-ray diffraction analysis (XRD), microscopy, and aqueous leaching and chemical analysis. The results demonstrated that the waste rocks of the Ak-Sug deposit were generally not potential sources of acid mine drainage (AMD). Notably, 50% of the samples contained arsenic at levels up to 10 g/t, with a maximum content of 450 g/t observed. Moreover, the study revealed that Me(H2O)6^2+ species of copper, zinc, and cadmium began to predominate in acid drainage solutions. The dissolution of aluminum, iron, and manganese phases was also noted, along with the desorption of metals in acidic solutions. Overall, the research provides critical insights into the geochemical behavior of waste rocks in relation to potential environmental impacts associated with mining activities.
