    The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) The iron ore is crushed and the waste rock is removed. About 85 % of the particles should be less than 44 μm (in length, width, or height)

    The process is considered more efficient than making use of iron ore powder, which does not allow the hot air to freely circulate and warm the ore to a uniform temperature. For this reason, the pellets are often preferable to fine iron ore products, since the ability to achieve that balance in temperature is somewhat limited with the fine ore

    Mar 21, 2015 Iron ore pellets can be made from beneficiated or run of mine iron ore fines. Lean iron ores are normally upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized so that it can be used in an iron making process. Also during the processing of high grade iron ores which
