High-grade hematite direct shipping ores generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products. Low-grade hematite ores require additional beneficiation to achieve the desired iron content, but the comminution of these ores still ...

The high grade hematite iron ores require simple crushing and washing. As the grade of ore is declining, run-of-mine ore needs intense washing before shipment. Depending upon the origin and mineralogical characteristics of the ore, beneficiation methods vary from simple crushing and screening to complex concentration processes.

Optical sorting test results of hematite ore and lignite were evaluated together on ROC space (Fig. 17). Although using % Fe grade of hematite sample and % ash content of the lignite sample caused a shift to the right on the ROC space, the effect of particle size and feed rate on the separation performance was well demonstrated.
