Four kinds of chemical waste salt as raw materials were treated by high-temperature treatment method.The temper-ature conditions of organics removal of four kinds of chemical waste salt were investigated.The product salt composition and organics removal effect after high temperature treatment were analyzed.The test results indicated that the organics in waste salts decreased gradually with the increase of temperature;X-ray fluorescence spectroscopy（XRF） and X-ray diffraction（XRD） results revealed that the organics in the chemical waste salts were almost removed after heating in the electric furnace for 60 min at 800 ℃,and the salts were melted and produced as molten salts.After cooling,crushing and impurity removal for the molten salts,the product industrial salt was obtained.The process realized the harmless treatment of chemical waste salt.
Key words： chemical waste salt; harmless; high temperature treatment
