The iron ore concentrating process aims to increase the iron content by removing impurities (gangue minerals) such as silica, alumina, and phosphorus. The specific method depends on the type of iron ore (magnetite, hematite, etc.) and its mineralogy. Here are the key steps in a typical iron ore concentration process:
