Arsenic Removal from Mine Tailings for Recycling via
Abstract. In this study, we propose a flotation process to remove the arsenic from Samkwang mine tailings in South Korea, which contained a high arsenic content, in order to render them suitable for recycling. In order to maximize the arsenic removal from the mine tailings, three variables (type of collectors and activators, and solution pH ...

Treating Arsenic and Selenium in Mine-Influenced Waters
2019-1-22 · Acid rock runoff or acid mine drainage requires treatment because, untreated, it makes water uninhabitable for aquatic life. Contaminants such as arsenic and selenium can occur in both acid mine drainage and mine-influenced waters that have a neutral pH, depending on local conditions. In both cases, these two contaminants also require treatment.
