Insight into acid generation and the release risk of Cd, Cu and Mo from a high-latitude polymetallic mine in China.

ABSTRACT: Considerable amounts of heavy metals can be released through mining activities, and different heavy metals, such as Cd, Cu and Mo exhibit varying release behaviors from tailings and ores under similar conditions; therefore, the insight to their release risk for tailings, waste rock, and ores is crucial for developing protection strategies for mines. In this study, samples of tailings, ores, and surface water were collected from a high-latitude polymetallic mine in China to investigate the risk of heavy metal release. Relatively high concentrations of heavy metals such as Cd, Cu and Mo were found in tailings and some ores. However, tailings were classified as nonacid generation indicating a low release risk of heavy metals, and only some ore samples (DBS2, DBS3 and DBS5) with high concentra
