Abstract: The paper analyzes the present iron ore resource conditions; reviews the current typical separation processes including process of gravity separation-low intensity magnetic separation-high intensity magnetic separation-reverse flotation, total low intensity magnetic separation process, low intensity magnetic separation- flotation combined process, and roasting-low intensity magnetic separation-high intensity magnetic separation-reverse flotation; summarizes the highly effective separation equipment including high intensity magnetic separator, magnetic separation column, CSX magnetic-field screener, high frequency vibrating fine screen and cyclonic-static micro bubble flotation column; reviews the progress in iron separation technology; and looks forward to the development trend of iron separation.

Key words: Iron ore, Gravity separation, Magnetic separation, Reverse flotation, Roasting
