Abstract: The main chemical constituents and dissemination characteristics of main mineral of a hematite were introduced, based on the idea of early throwing,coarse and fine separation, experimental study of combined process flow of low intensity magnetic separation,high intensity magnetic separation,table concentration and so on were done on raw ore which the total iron grade is 35.50%, concentrate with total iron grade 57.74% and recovery rate 75.98% are obtained.

Key words: Hematite, Classification, High intensity magnetic separation, Gravity separation
