Mineralogical and Chemical Characterization of Low Grade Iron Ore
The depletion of high grade iron ore resources make it inevitable to utilize the existing low grade iron ores/fines/tailings with effective beneficiation to meet the present specification and demand. In this work, a mathematical model for the straight-grate pellet induration furnace is presented.Drying of a porous bed of iron ore pellets is here considered by modeling a discrete two-dimensional system of round pellets. As a complement to the two-dimensional model, a continuous one-dimensional model enabling fast calculations is developed. Results from the discrete model show that the temperature front advances faster in Discrete and Continuous Modeling of Heat and Mass Transport in
