Low Grade Iron Ore Processing Hematitel

Jan 13 2020 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.
