Sustainable Mining and Metallurgy

This paper reviewed the development history of hazardous waste industry in China, analyzed the advantages and disadvantages of current industrial hazardous waste disposal technology and highlighted the principle and core development of SCC independently developed by China ENFI as well as its promotion and application in the hazardous waste disposal industry. SSC refers to the injection of oxygen-enriched air and fuel into the bath through the side-blowing lance at an approximately sound velocity, making the fuel fully burnt in the bath and providing energy for the reaction. Meanwhile, the gas injected by lance and produced from combustion stirs the bath and accelerates the heat and mass transfer in the bath. The core equipment for industrial hazardous waste treatment is the comprehensive recovery treatment furnace. SSC is characterized by advantages of strong adaptability of raw materials, high availability, good safety, low dust yield and high recovery date of valuable metals, which can achieve hazard-free disposal of industrial hazardous waste and comprehensive resources recovery.
