In the production of hot briquetted iron some fine by-product is generated. This material consists mainly of metallic iron and iron oxides. Before utilization of these fines in the steel mill and/or direct reduction plant, agglomeration is required. To get briquettes with sufficient strength a binder has to be added to the fines.

The agglomeration of solid wastes is a key factor for subsequent utilization, while the difficulty in agglomeration and high cost have become common problems in the recycling process. The disk pelletizing process was adopted, based on the optimization method by liquid binder addition, and the influence mechanism of the ratio of typical …

Starting from a crude ore assaying 45.6% Fe, a fine-grained oolitic iron ore was concentrated by the oil agglomeration technique to 90% Fe recovery and 65% Fe assay. The ore required grinding to minus 5 μm to effect adequate liberation, and the technique yielded optimum results at pH 9. The roles of pH, collector, and bridging liquid …

12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …

Iron ore powder agglomeration is the basis for blast furnace ironmaking and is the processing work in between ore crushing, ore grinding separation, and steelmaking. Its purpose is to provide high-quality furnace burden for steelmaking. It is an important …

Fines iron ore oxides are generated during mechanized mining as well as comminution, beneficiation, transportation, and agglomeration processes. These iron ore fines need to be taken care of and reused in ironmaking. The present work focuses on the utilization of those fines by agglomeration techniques and converting them into reduced …

Inclusion agglomeration is an important element in several industrial problems during steelmaking, such as nozzle clogging. In parallel work by the authors, a revised Kralchevsky-Paunov model has been established and the performance of this model has been validated against the experimental data from in-situ observations using …

It is found that the high tendency of unsupported manganese‐iron oxide particles towards agglomeration can be improved with any of the chosen additives. The particles with CeO2, and especially ...

Abstract. Dispersion and agglomeration control the macroscopic properties of nanocomposites; thus, quantitative characterization of particle dispersion and agglomeration is crucial. So far, methods such as image analysis or measurement of macroscopic properties have been insufficient. So, a novel methodology is introduced to …

ABSTRACT In steel industry and in mines, a significant amount of ultra-fines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice. However, sintering has a limitation of accepting ultra …
