1.1.3.2.1.2 Iron-Bearing Materials. Ore fines and iron concentrates make the main part of the sinter mix. The grain size of ore fines and concentrates is typically 0–8 and 0–3 mm, respectively.Grains smaller than 0.1 mm are not desired because they reduce the gas permeability of the bed and thus decrease the sintering efficiency.Recycled materials, such as …

Effect of Coarse-grain and Low-grade Iron Ores on Sinter Properties
In sintering of iron ore, small particles act as a binder that joins larger particles through diffusion and melting. In order to understand the effect of gangue and structure of coarse ore on sinter properties, melt formation in three coarse-grain, low-grade iron ores was investigated. The melt fractions at the sintering temperature were ...

Role of iron ore in enhancing gasification of iron coke: Structural
The kinetic study indicates that the random pore model can effectively represent the gasification process of iron coke due to its rich pore structure. Moreover, as the proportion of iron ore increases, the activation energy for the carbon gasification gradually decreases, from 246.2 kJ/mol for coke to 192.5 kJ/mol for iron coke 15wt%. ...

Extraction of Iron from Hematite
Carbon monoxide reduces the iron(III) oxide in the iron ore to form iron This will melt and collect at the bottom of the furnace, where it is tapped off: iron(III) oxide + carbon monoxide → iron + carbon dioxide. Limestone (calcium carbonate) is added to the furnace to remove impurities in the ore.
