Abstract: Industrial application of acid treatment from Zijinshan copper mine was summarized. According to the properties of drainage and characteristics of water yield, comprehensive recovery of valuable metallic elements and drainage recycling or discharging within the standard have been obtained through membrane separation technology, extraction technology, sulfuration sedimentation, neutralization system. Current status for drainage discharge control from the origin was stated. Aiming at the problems of neutralize residue heaping, control from the origin of discharge and end-treatment will the tendency in the future.

Key words: Acid mine drainage, Copper, Membrane separation, Extraction, Sulphurization, Neutralization process
