Experimental study demonstrates the removal efficiency of steel slag for heavy metal ions in acid mine drainage, suggesting a viable treatment method.
Basic oxygen furnace (BOF) slag was employed as a sorbent to treat acid mine drainage (AMD) composed of Fe(II), Mn(II), Zn(II), and Cu(II). Single-factor batch experiments, combined with characterization of the slag before and after adsorption, were conducted to evaluate its removal performance for each metal ion. In the AMD treatment process, the extraction efficiency of the metal ions decreased with increasing slag particle size and with higher initial heavy metal ions concentrations. The initial adsorption rates in competitive adsorption followed the order Fe(II) > Mn(II) ≥ Cu(II) > Zn(II). The extraction of Fe(II), Mn(II), Zn(II), and Cu(II) from the simulated AMD conformed to the pseudo-second-order kinetic model together with the Freundlich isotherm model, indicating that multilayer adsorption dominated and the active sites on the slag surface were inhomogeneously distributed.
