Abstract The high concentrations of Fe2+ and Mn2+ in acid mine drainage make
it difficult and expensive to treat. It is urgent that we find a cheap and efficient
adsorption material to treat Fe2+ and Mn2+. As a solid waste in mining areas, coal
gangue occupies a large area and pollutes the surrounding environment during the
stacking process. Developing a method of resource utilization is thus a research
hotspot. In this study, we modified spontaneous combustion gangue using NaOH,
NaCl, and HCl by chemically modifying the minerals. We determined the optimal
conditions for treating Fe2+ and Mn2+ in acid mine drainage… More >
