Beneficiation Of Banded Magnetite Quartzite Ore

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 the release of iron values
