How to Process Hematite: Beneficiation Methods and Project ...

May 27, 2021  Hematite, weakly magnetic iron ore with better floatability than magnetite and wide distribution, is one of the most important raw materials for ironmaking.. Its composition is complex. In addition to containing a small amount of magnetite, the impurity embedding of hematite has uneven particle size and high content of fine particles, which often requires some beneficiation processes.

The rate of reduction of both iron ore and quartz varies (Figures 1 to 3). Quartz dissipates easily, breaking down to fines with little applied stress. Though the hardness value of quartz (i.e. 7 on the Mohr’s scale) is a bit higher than the iron ore (Hematite (5.5-6.5), Magnetite (5.5-6), it is far more brittle than iron ore (Gribble, 1988).
