    ABSTRACT. In this study, low grade hematite ore s from E ğmir Balık esir, T URKEY were upgraded to obtain a. hematite concentrate to be used in iron and steel industry. Processing of Banded Hematite Quartzite Ore for Recovery,2020-1-13 · This study investigates upgrading of low-grade banded hematite quartzite iron ore (Fe ~31%). Conventional beneficiation was found to be futile. The susceptibility of iron phases to microwave exposure and their selective absorption assists in the liberation of iron values. Microwave exposure of coarse particles at 540 W for 10 min yielded a concentrate with Fe 56.30% and recovery of 50.68%
