From: Dynamics in leachate chemistry of Cu-Au tailings in response to biochar and woodchip amendments: a column leaching study

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, fresh tailings from ore processing; EHM_leached, tailings after 6-month leaching in the column leaching experiment; EHM + 10% biochar, tailings with 10% biochar amendment and after 6-month leaching in the column leaching experiment; EHM + 20% woodchips, tailings with 20% woodchip amendment and after 6-month leaching in the column leaching experiment.
