Abstract: This article has carried on an investigation in cement solidification,medicament stabilization and combination of both to dispose the zinc metallurgical slag.The result indicates that if cement solidification and medicament stabilization are combined to dispose the zinc metallurgical slag,the content of heavy metal in the leaching solution is under the Chinese Identification standard for hazardous wastes,which can control the pollution to the environment effectively.So the method of using the combination of cement solidification and medicament stabilization to dispose hazardous waste is completely feasible.
