Selective Flocculation of Banded Hematite Quartzite (BHQ) Ores. Aug 18, 2011 banded iron ore formation (BIF)banded hematite quartzite. (BHQ) consist of bands of ironbearing hematite or magnetite inter growth with quartz beneficiation techniques that have been tried to
generated during mining and processing of the ore. 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 nature of the ore which is difficult to treat by straightforward
#0183;#32;Upadhay et al. presented an extensive study on the mineralogical and beneficiation aspects of such banded ores available in the eastern region of India. Using selective flocculation method, Panda et al. have beneficiated banded hematite quartzite with a feed of 38% Fe to a concentrate of % Fe with 92% iron recovery.
To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The BHQ ore was assayed as
#0183;#32;In this study, banded magnetite quartzite iron ore (Fe ~ 41%) is physically beneficiated and microwavetreated followed by lowintensity magnetic separation. The appearance of massive random cracks during microwave treatment assisted the release of iron values from the matrix. Magnetite phase is strongly receptive to microwave exposure, thereby
Quartzite (BHQ) and Banded Hematite Jasper (BHJ) and occupies sixth position in the world iron ore reserves. [1, 2] Although India is blessed with large reserves of iron ore, a substantial amount of
16/12/2010 To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The BHQ ore was assayed as % Fe, % SiO 2, and % Al 2 O 3.

The effective utilization of lowgrade banded iron ores is inevitable to meet India Steel Vision 2030 of producing 300 MT steel. In this study, banded magnetite quartzite iron ore (Fe ~ 41%) is physically beneficiated and microwavetreated followed by lowintensity magnetic separation. The appearance of massive random cracks during microwave treatment assisted the release of iron values from
#0183;#32;The investigations on the beneficiation of banded iron ores (BHQ, BHJ, and BMQ) are limited and mainly involve processing techniques such as flotation, highintensity magnetic separation, jigging and reduction roasting (Rath et al., 2014, Das et al., 2010, Makhija et al., 2013).
#0183;#32;Indian hematite deposits belong to the Precambrian iron ore series and the ore occurs as banded, laminated, friable and also in powder form. During conventional mining of hematite ores, there is a significant generation of low grade banded iron ores such as BHQ, BHJ, and BMQ which ends up in unused stockpile at the mine sites due to a lack of suitable beneficiation technology ( IBM, 2017
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 magnetite.
