Role of multiple substrates (spent mushroom compost, ochre, steel slag, and limestone) in passive remediation of metal-containing acid mine drainage
The potential of selected materials in treating metal-rich acid mine drainage (AMD) has been investigated in a series of batch experiment. The efficiencies of both single and mixed substrates in AMD treatment under two conditions i.e. low and high concentration solutions containing heavy metals were...

| description | The potential of selected materials in treating metal-rich acid mine drainage (AMD) has been investigated in a series of batch experiment. The efficiencies of both single and mixed substrates in AMD treatment under two conditions i.e. low and high concentration solutions containing heavy metals were evaluated. Synthetic metal-containing AMD was used in the experiments treated using spent mushroom compost (SMC), ochre, steel slag (SS) and limestone. Different ratios of treatment materials were incorporated in the substrate mix and were tested for AMD treatment in an anoxic condition. In the batch test, physicochemical parameters (pH, redox potential, total dissolved solids, conductivity, Ca concentration) and heavy metals (Fe, Mn, Pb, Zn, and Al) were analysed. Overall, the mixed substrates have shown satisfactory performance in increasing pH with increasing Ca concentration and removing metals. It has been found that SS and ochre played an important role in the treatment of AMD in this study. The results showed that the mixed substrates SM1 (i.e. 10% SMC mixed with 20% ochre, 30% steel slag and 40% limestone) and SM2 (i.e. 20% SMC mixed with 30% ochre, 40% steel slag and 10% limestone) were effective in increasing the pH from as low as 3.5 to 8.09, and removing heavy metals with more than 90% removal efficiencies. |
