Petrology and Geochemistry of the Banded Iron

Quartzite is the main ore-bearing rock with magne-tite mineralization, and gangue minerals include quartz, biotite and minor plagioclase. Based on the content of magnetite, the quartzite can be divided into two types: quartzite with minor magnetite (Mt%< 15 %; Fig. 4d,f; Type A), and high-grade magnetite

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 .
