Resum
Acidic mine waters (AMWs) contain, in addition to moderate concentrations of sulphuric acid, relatively high concentrations of transition elements (e.g. Fe, Al, Cu, Zn) and, in some cases, minor amounts of valuable rare earth elements (REEs). The established management routes for AMWs, based on the neutralisation and metal stabilisation as hydroxides, are limited by the associated costs, such as reagent consumption. Nanofiltration (NF)-based treatment processes could improve these management rou...
