Acid leaching of heavy metals from bentonite clay, used in the cleaning of acid mine drainage

open access: yes, 2010
Heavy metals and sulphates in acid mine drainage (AMD) can be adsorbed onto bentonite clay, leaving clean water and a heavy metal loaded clay precipitate as products. Due to the toxicity of heavy metals, the clay could not be disposed of safely in the
