Granulation - an overview ScienceDirect Topics

L. Lu, O. Ishiyama, in Iron Ore, 2015. 14.2.1.3 Chemical characteristics of iron ore. Granulation is generally considered to be a physical process involving the physical interactions of particles mainly through capillary forces. The influence of ore chemical characteristics on granulation is therefore largely neglected in the literature. However, from the authors' experience on deslimed ores, the desliming process was found to affect the granulation efficiency of ore

The production of granulated iron ore is usually done dry and without the use of water. In this method, using magnetic methods, high-grade iron ore is separated from low-grade iron ore. Since this type of iron ore has a low grade, it can not be used in the direct reduction system, but it can be used in blast furnaces. Of course, in deposits, the average grade of iron ore is low and the amount of elements is too acceptable. Today, in the iron ore
