This study investigated the removal of vanadium from mining waters at a closed mine site (Mustavaara, Finland) using granular ferric oxyhydroxide (CFH-12) on pilot scale. Two filter systems, A and B, were placed in different streams, where influent contained higher very variable concentration (6.46–99.1 mg/L), while B treated had lower concentrations (0.443–2.33 mg/L). The operation periods 51 ...
