A New Approach of Pelletizing: Use of Low-Grade Ore as a
The pelletizing process mostly uses high-grade iron ore such as magnetite (Fe3O4) as the main raw material, which has been depleted due to the increasing demand for pellet production. The current study attempted to replace magnetite ore with low-grade limonite ore (Fe2O3∙nH2O) at different additional levels (10, 30, 50 and 100 wt%).
