Tailing ponds are major sources of heavy metal pollution. Previous studies primarily focused on tailings with high sulfur content, limited attention to low-sulfur tailings. This study explored the release behavior Pb, Zn, and Cd from under simulated acid rain conditions, considering factors such as pH, particle size, weathering degree. Samples were collected a lead–zinc tailing pond in karst regions northern Guangxi, China. Batch leaching experiments indicated that even neutralization capacity (ANC = 166.57–167.45 kg H2SO4/t), substantial occurred acidic conditions (pH 2–3), concentrations increasing 4–6 times compared neutral conditions. Leachate slightly higher coarser particles than finer ones, while further enhanced release, particularly for Cd. These findings suggest alone may not be sufficient prevent exposed rain. However, due laboratory scale this study, validation through field-scale or mesocosm is necessary confirm observed trends assess their implications environmental risk management regions.
