2.1 Material 2.1.1 Sample Collection. Indian iron ore was collected from Kiruburu mine's Jharkhand, in the form of fines (<5 mm). Afterward, the ore concentration was found to be 62.42% Fe, 2.98% SiO 2, and 1.91% Al 2 O 3 and presented 3.61% LOI. Since it has a significant LOI percentage, drying and induration of the ore is imperative …
In order to be able to estimate the values of α av using the Blaine's air permeability method, it was decided to use the mean values of the experimentally determined α av for the filtration and percolation stages, and t tr during the filtration experiments. These values were applied in determining the further correlations.
Pelletizing is the process of converting iron ore fi nes into "Uniformed Sized Iron Ore Pellets" that can be charged into the blast furnaces or for Production of Direct Reduced Iron (DRI) [1]. 1. Process objective is to transform fi ne iron ore concentrate into pellets suitable to feed Blast Furnace or Direct Reduction plant or COREX. 2.

The results showed improved properties of iron ore pellets at an optimum Blaine number (2150 cm 2 /g) but, reduction degradation index was found to be very poor for the given ore. Further investigation showed that when MgO containing flux viz. pyroxenite was added, the reduction degradation index and swelling index of the pellets …
The Blaine number of iron ore concentrate is a key parameter in the iron and steel chain, especially pelletizing. In this study, a novel and comprehensive strategy was introduced for modelling and estimating the Blaine number of iron ore concentrate by using the particles physical properties (particles size distribution and shape)-based …

What is iron ore pellet. Iron ore pellets are made by adding a small amount of additives to the fine ore powder (-200 mesh, that is, the ore powder with a particle size of less than 0.074mm accounts for more than 80%, and the specific surface area is more than 1500cm2/g), adding water to the pelletizer, relying on capillary force and mechanical …
Canadian iron concentrate (CIC) can elevate the ferrous grade and lower the contents of gangue components and harmful elements in the sinter. To understand high-temperature characteristics of CIC and typical iron ore, the formation of the melt was calculated mainly through FactSage 7.2, and melt fluidity (MF) test for iron ore fines and …
