Improper mining activities cause water, soil, and air pollution. They may cause problems affecting all living things in the area where the activity is carried out and in the nearby geography. Therefore, the economic development to be obtained from mining should be evaluated together with the environmental problems it will cause. The contemporary approach in this regard should be to take environmental protection measures by predicting the problems that may occur with good planning, monitoring, and environmental technologies, and to ensure that the development is continuous and sustainable. In this context, samples were taken, and initial analyses were performed to examine the environmental impacts of the waste ponds in the mining operation in Balıkesir (Türkiye). Accordingly, it was observed that lead and zinc were in high concentrations in the region. Sulfide-Sulfur (SO₃2—S2−) tests were performed and it was determined that the area’s waste and mining waste produced acid and were harmful to the environment. In this study, the cemented paste backfill (CPB) method was applied to the samples to intertie waste and prevent acid production. Leaching tests were performed on the sample that completed the 28-day curing period from the CPB mixtures prepared using mining waste. The leaching test was applied to the waste samples to achieve this objective, with results remaining below the regulatory limit values. Acid mine drainage (AMD) tests showed that CPB samples which were cured for 28 days had no acid generation potential. Pyrite was determined to be the primary mineral responsible for acid formation, while neutralizing minerals were found to belong to carbonate and silicate groups. CPB application decreased acid-forming minerals by increasing the neutralization capacity.
