iron ore green pellet characteristics

Green Pellet an overview ScienceDirect Topics

Jan 01, 2012· Iron ore fines are mixed with pulverized coal, agglomerated into green pellets. The pellets are fed to an RHF, heated to 1623–1723 K, and reduced, melted in the RHF within approximately 10 min and then discharged. The gangue and ash contained in the pellets are melted to separate metallic iron and slag in the RHF.

Iron ore pelletizing liming Outotec

Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help

Binding mechanisms in wet iron ore green pellets with a

Industrial iron ore green pellets are over-saturated and a supporting “network” of viscous liquid is formed on the green pellet surface. At least half, probably more, of the total binding force appeared to be due to the cohesive force of the network. The other half (or less) of the total compression strength can be explained by the

Iron Ore Pelletizing Process: An Overview IntechOpen

Jul 10, 2017· 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. This chapter shows the status of the pelletizing
