    The quartzite with minor magnetite (Type A) was dominantly composed of quartz (>90 %), which ranged from 01 mm to 03 mm in size, and small amounts of magnetite, biotite (Fig 4e) and plagioclase (Fig 4g) The banded magnetite quartzite (BIFs) are the main ore type (Fig 4h), which is dominantly composed of magnetite and quartz The contentRecovery of iron values from banded magnetite quartzite (BMQ) ore by direct and reverse flotation technique is presented In direct flotation, with oleic acid as the collector, the iron grade in the concentrate that could be achieved is limited to 57% Fe from a feed containing ~ 47% FeThe difficulty of concentrating iron values by direct flotation technique is due to the fine coating of ironProcessing of banded magnetite quartzite (BMQ) ore using1 Introduction Banded iron formations (BIFs) are marine sedimentary rocks that formed in voluminous amounts during the Late Archean, with a peak of deposition at ~ 25 Ga (Klein, 2005)BIFs typically contain alternating magnetite (Fe 3 O 4) or hematite (Fe 2 O 3)dominated ironrich layers, and microbanded iron oxidebearing silicarich and ironpoor layersGeochemistry and Si–O–Fe isotope constraints on the
