MELTING TREATMENT METHOD OF INDUSTRIAL WASTE

摘要

PROBLEM TO BE SOLVED: To provide a melting treatment method of industrial wastes capable of performing stable operation by putting the SiOconcentration of molten slag in a proper range while suppressing the generation of furnace iron.SOLUTION: In a melting treatment method of industrial wastes where industrial wastes including at least metallic iron is melted in a melting furnace, at least converter slag at copper smelting is added to the industrial wastes and a ratio Fe/SiO(mass% ratio) in obtained molten slag is adjusted to be in the range of 0.4-0.8.SELECTED DRAWING: Figure 1
