Use of Basic Oxygen Furnace (BOF) Steel Slag for Acid Mine
Jul 19, 2019· We investigated the feasibility of using alkaline basic oxygen furnace (BOF) steel slag to treat acid mine drainage (AMD). Simulated AMD was treated with different doses of slag (10, 20, 30, 40, 50, and 60 g/L) for 24 h in batch reactors. A dose of 30 g/L was considered optimal because it raised the pH to 8.6 and resulted in 99% removal of trace metals in 24 h.
