Passive mine water treatment system was used for the treatment of the mine water, and consisted of SAPS(Successive Alkalinity Producing System), OP(Oxidation/settling Pond) and wetland, etc. This study was carried out for physical and chemical analysis of sludges of Waryong, Donghae (6th adit) and Honam mine to investigate the basic properties of the sludges settled in the passive mine water treatment system. The water content of the sludges collected from SAPS was found to be about 50% to 72% and that of the sludges collected from OP was found to be about 59% to 73%. The particle size of sludges was various. From the XRF analysis, the content of Fe2O3 was over 70% at most sludges. The Cd concentration of sludges from the ICP-OES analysis exceeded the soil contamination standards of the heavy metals.
