There has been a steady increase of iron ore demand in the last few decades. This growing demand could be countered by use of low grade iron ore after beneficiation. Banded iron formations (BIF) are one of the resources of such low grade iron ores. Banded magnetite quartzite (BMQ) is one such BIF and a source of iron phase mineral in the form of …

1. Introduction. Banded iron formations (BIFs) are characterized by their alternating iron-rich and silica-rich layers that were precipitated throughout much of the Late Archean and Paleoproterozoic (2.7–1.9 Ga) (Klein, 2005, Bekker et al., 2010).The main mineralogy of the least metamorphosed BIF consists of chert (SiO 2), magnetite (Fe 3 …

Magnetite is the major iron-bearing mineral in many BIFs (particularly in the Archean) and is variably interpreted to be of primary, early diagenetic, or metamorphic origin. Different genetic interpretations for magnetite lead to divergent pictures of the Precambrian Earth system and its evolutionary models through time.
