Figure 5 Dynamic of Fe in the first 50-ml leachate over sixcycles of leaching. EHM, pure tailings; EHM + 20% woodchips,tailings with woodchip; and EHM + 10% biochar, tailings withbiochar amendment.
Figure 6 X-ray diffraction (XRD) patterns for tailing samples used in this study. Prominent peaks were assigned as shown in the figure.EHM_weathered, tailings collected from the tailings impoundment weathered for several years and used for column leaching; EHM_fresh, freshtailings from ore processing; EHM_leached, tailings after 6-month leaching in the column leaching experiment; EHM + 10% biochar, tailings with10% biochar amendment and after 6-month leaching in the column leaching experiment; EHM + 20% woodchips, tailings with 20% woodchipamendment and after 6-month leaching in the column leaching experiment.
