Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces.
