Abstract: The prevention and treatment technology of geochemical engineering (PTTGE) on acid mine drainage (AMD) is a sort of geochemistry method (including the prediction and assessment of AMD, the covering and the permeable reactive barriers) to predict and on-site treat the AMD (and heavy metals) contamination based on the AMD origin mechanism. The PTTGE is worth popularizing in China, because it has a lot of advantages, such as the longevity, low price, easy construction, on-site remedy, and especially it can be used to treat the acid waters enriched with the toxic heavy metals, characterized by the high discharge, long time flow.

Key words: Sulfide mine, Solid waste, Acid mine drainage, Geochemical engineering
