Mineralogical and Geochemical Characteristics of the Precipitates in Acid Mine Drainage of the Heungjin-Taemaek Coal Mine

초록

Research Highlights The behaviors of heavy metals during the transformation of ferrihydrite to goethite were investigated for core samples from an AMD treatment system in the Heungjin-Taemaek coal mine. The concentration ratio of As, Cd, Co, Ni, and Zn to Fe decreased with the increasing transition of ferrihydrite to goethite with depth. As showed the highest affinity with Fe during the precipitation of ferrihydrite and transformation to goethite.
