Processing of banded magnetite quartzite (BMQ) ore

2014-4-1  Banded magnetite quartzite (BMQ) ore occurs as separate veins in iron ore mines and recovered while mining the natural hematite ore. In India, such ores are considered as low grade iron ores with Fe content of 25–45%, SiO 2 30–60% and Al 2 O 3 1–5%. No commercial plant has been set up so far to recover the iron values from such ores for any industrial applications.
