These three-dimensional models allow the deformational characteristics of the banded iron formation to be quantified on a hand specimen scale. Petrographic analysis showed that the banded magnetite quartzite has experienced brittle deformation, and electron microprobe analysis revealed iron enrichment in the fold axes.
Banded Magnetite Quartzite occurs near the village Allipur, Somavarampet contain low grade iron ore in the form of banded magnetite haematite quartzite with their iron ore content ranging between 40-45%. In these ferruginous bands iron oxides forms only about 1/3rd of the total rock, the remaining being mostly silica and silicate minerals.
Understanding the Challenges of Hard Rock Mining in Ethiopia’s Diverse Geological Landscape Ethiopia’s geology is a treasure trove of hard rock formations, from the Precambrian basement …
Similarly, the process to recover iron values from the banded iron ore formation (BIF)—banded hematite quartzite (BHQ), banded hematite jasper (BHJ) and banded magnetite quartzite (BMQ)—are yet to be explored due to the fine na-ture of the ore which is difficult to treat by straight-forward selective flocculation means.

The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz and mineral content of Banded iron formation includes Hematite, Magnetite, Quartz.
The reserve of good quality ores is dwindling sharply, and the major iron ore resources that would be available in future are limited to lean ores, such as banded hematite quartzite (BHQ), banded hematite jasper (BHJ), and banded magnetite quartzite (BMQ). These ores contain averagely 30wt%-40wt% Fe. The formation of these ores are the result of residual concentration of iron …
2020113· 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 …
