ABSTRACT - Acid mine drainage from Robule Lake is treated by neutralization process. Generated sludge is reach in copper and because of that is treated by leaching process, during which generate new type of waste. Characterization of this type of waste shows that is non-hazardous waste with high mobility of sulphate ions in leachability test and high mobility of lead and cadmium ions in toxicity test. Developed stabilization process shows low influence on immobilization of sulfuric ions, but high influence on immobilization of cadmium and lead ions presents in solid waste.
