High-pressure grinding rolls (HPGR) have gained great popularity in the mining industry in the last 25 years or so. One of the first successful applications of the technology has been in iron ore pressing prior to pelletization. Piston-and-die tests can provide good insights on the material response in an HPGR. This work analyzed …
High-pressure grinding rolls reached great popularity for pressing iron ore concentrates since its first application in the 1990s. For this particular application, mathematical models describing HPGR performance on the basis of operating conditions and feed characteristics have successfully been used by the authors to map industrial …
Blaine specific surface area (SSA) is an essential physical property of iron concentrate and is availably improved by a high-pressure grinding roller (HPGR) to enhance the pelletability and the qualities of oxidized pellets. In this study, the four concentrates with various SSA were obtained by HPGR treatment to produce the oxidized pellets. The …
The Blaine number (cm2/g) of the fines is an essential parameter in defining the quality of the pellets. The Blaine number of the fines influences the overall reactivity, porosity, and agglomeration capability of pellets. Pal J et al. have studied the quality of the pellets for different sizes of iron ore fines in terms of Blaine number [14].
The Indian hematite iron ore concentrate maintains high LOI because of the presence of kaolinite, goethite and gibbsite even after beneficiation process. As this ore is in fragile nature, the Blaine number of pellet feed material is high. To maximize the iron values from the slimes and tailings, flotation process may be adopted in future.
Mineral deposits frequently contain several elements of interest that are spatially correlated and require the use of joint geostatistical simulation techniques in order to generate models preserving their spatial relationships. Although joint-simulation methods have long been available, they are impractical when it comes to more than three variables and mid to …

The typical properties of the iron ore pellets are given in Tab 1. Process technology. There are four stages involved in the production of iron ore pellets. These stages consist of (i) raw material preparation, (ii) formation of green balls or pellets, (iii) induration of the pellets, and (iv) cooling, storage and transport of pellets.
