TREATMENT METHOD OF IRON-MAKING DUST, RECYCLING METHOD OF IRON-MAKING DUST, AND METHOD OF MANUFACTURING GRANULATE PRODUCT OF IRON-MAKING DUST

摘要

To propose a treatment method of iron-making dust capable of treating iron-making dust while suppressing oxidation of metallic iron and ferrous oxide contained in the iron-making dust, a recycling method of iron-making dust, and a method of manufacturing a granulate product of iron-making dust.SOLUTION: The treatment method of iron-making dust containing metallic iron, and iron oxide generated in an iron-making process includes: a water content-adjusting process of adjusting a water content of the iron-making dust; a pH-adjusting process of adjusting a pH of the iron-making dust; a binder-adding process of adding a binder to the iron-making dust adjusted with regard to a water content and a pH; and a granulating process of granulating the iron-making dust added with the binder.SELECTED DRAWING: None
