Chemical characterization involves the analysis of iron ore and agglomerates, analysis of coke and lime stone. The major constituents of iron burden are Fe203, FeO, Si02, A1203, and the traces elements like Cu, Ni, Co, Pb, Zn and,Mn. Through chemical analysis, the quality of iron burden for the blast furnace can be assessed prior to its charging.

Flocculation - Wikipedia

Flocculation is synonymous with agglomeration and coagulation / coalescence. Basically, coagulation is a process of addition of coagulant to destabilize a stabilized charged particle. Meanwhile, flocculation is a mixing technique that promotes agglomeration and assists in the settling of particles.

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...
