At grain sizes below 100 µm, impurities such as silica and alumina are separated from the iron ore in a sequence of beneficiation steps, depending on the mineralogy of the iron ore. Removal of impurities from the iron ore is done prior to subsequent processing in pelletizing plants and direct-reduction plants.
