Microwave Processing of Banded Magnetite Quartzite Ore
2019-3-13 · The effective utilization of low-grade banded iron ores is inevitable to meet India Steel Vision 2030 of producing 300 MT steel. In this study, banded magnetite quartzite iron ore (Fe ~ 41%) is physically beneficiated and microwave-treated followed by low-intensity magnetic separation. The appearance of massive random cracks during microwave treatment assisted

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
