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 …

The blaine number of iron ore concentrate is important for pellet feed specification which is measured by air permeability apparatus and its unit is cm2/gr, while specific surface is measured by ...
Blaine specific surface area (BSA), an important parameter used to characterize the fineness of powdered materials, is commonly used to control pellet feed quality in iron ore pelletizing plants [43].
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.
For iron ore pellet feed preparation from fine iron ore concentrates, at sizes below 1 mm and generally at a high moisture content ranging between 7 % and 12 %, HPGR
Since high Blaine concentrate pursues finer particles of CaO, smaller pores are formed. ... and it is the minimum at 1350 °C for both Iron Ore and No.2 pellets. M.P.G.D. has more value in the aspect of Iron Ore No.2 due to high oxygen flow resistance. ... S.P.G.D. is higher for 200 mesh for both Iron Ore and No.2 pellets.

Iron ore concentrate is used as the fresh feed of pelletising plants. The green pellet properties depend on iron concentrate characteristics such as particle size distribution (PSD), specific surface area (Blaine value), iron grade, moisture content and grinding methods. The grinding methods affects particle size distribution and Blaine value.
Van der Meer and Leite (2018) showed that when pressing iron ore pellet feed with moisture contents above 8%, the Blaine specific surface area of the product was lower than the value reached for ...
WO2016127235A1 - System and process for dry recovery … The present invention relates to a system and to a process for dry recovery of iron oxide fines from iron-bearing compacted and semi-compacted rocks, comprising means for primary (5), secondary (6) and tertiary (7, 7') crushing for the purposes of preliminary reduction of the particle size …
The iron ore concentrate sample was composed by increments collected during 10 days from the concentrate thickener feed (Samarco's concentrator I). A resulting pulp weighing 1000 kg was dewatered, homogenized by conical piles and stored in 200 L drums. A riffles sample splitter was used to produce samples for the technological tests.
Optimum Blaine fineness of iron ore in the range of 1700–2250 cm 2 /g is usually used for good quality pellet making. However, when a material of high Blaine fineness is produced after beneficiation and there is no option to control the fineness, the pellet making from high Blaine fineness ore becomes obligatory. ...
