Pelletisation studies were carried out in laboratory by varying the ball mill discharge size from 52 to 68% -45micron size to optimize the pellet grade fines size to achieve …
Utilizing iron ore mining wastes like dump fines, slimes, and tailings, which contain significant iron values, is essential to meet future needs and environmental sustainability, requiring intensive research to develop a process that can identify the route for sustainable usage. Reduction roasting is a proven route for converting and …
16.1. Introduction. Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore resources.
The mill product, due to its physical properties, determines the efficiency of subsequent stages of classification, filtration and pelletizing, thus impacting the quality of iron ore pellets.
For pelletization study, as received iron oxide pellet fines were ground to below 150 μ using ball mill. The particle size distribution of ground iron ore fines was determined by the Malvern particle size analyzer (Hydro 2000MU, UK) and shown in Fig. 2.Blaine number was measured to determine surface area of the iron oxide pellet fines …
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 …

The generation of iron ore fines in dry processing plant of Khondbond region, India is about 30–40% of the total feed. The iron ore fine assayed 58.73% Fe (T), 5.54% Al 2 O 3, 6.6% SiO 2, and 4.37% LOI. Particle size distribution of fines showed that 50% (by weight) of material are below 1800 μm.
The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
