Because limonite is rich in crystal water, it is difficult to increase the grade of iron concentrate to more than 60% using physical beneficiation methods. The roasting method can significantly improve the grade of the concentrate. However, limonite is prone to mudification during crushing and grinding, resulting in a low metal recovery rate.

High iron content (+47.69%) limonite ore is moved to thickener and low iron content one to high intensity magnetic scavenger separation. the middlings are mixed with rough middlings for thickening process, while the rest ones are discharged as tailings.
