In many parts of India, because of depletion in high grade iron ore, efforts are focused on the use of lowgrade iron ore for steel production. As an alternative iron source, lowgrade banded iron ores have attracted attention. The beneficiation and utilization of banded iron ore is closely connected to their mineralogical characteristics, nature of impurity inclusion and liberation behavior.
A novel approach for the complete utilization of a lowgrade banded hematite jasper ore assaying ~ 47% Fe has been taken in order to address the issue of rapid consumption of highgrade iron ores and the rising concerns of waste disposal. The process includes the enrichment of Fe through reduction roasting followed by magnetic separation, and smelting of the nonmagnetic fraction to produce ...
ores of the study area can be classified as banded hematite jasper, massive ore, hard laminated ore, soft laminated ore, blue dust, flaky/friable ore, biscuit ore, martitegoetite ore, goethiticlateritic ore/Canga (recemented ore). The different types of ore often .
[4]. The direct flotation is supposed to be attractive in the case of low grade ores such as banded hematite quartzite (BHQ), banded hematite jesper (BHJ) and banded magnetite quartzite (BMQ) where the Fe content varies between 2535%. In spite of extensive research, perfect separation of hematite from quartz could not be accomplished [5].
· Banded hematite jasper is very hard in nature offers high resistance towards weathering. BHJ generally seen to represent most ridges. In Barsuan iron ore deposit, Banded Hematite Jasper occurs as the hanging wall and grades into Banded hematite chert and Quartzite (BHQ). This gradation only happens towards the southern side. 2.

· The banded iron formaton of Banded Hematte Jasper is a very ow grade ron ore that usuay contans Fe n the range of 3 040% depending on the origin. Banded hematite Jasper obtained from Barbil region of India and assayi ng % Fe, % SiO. 2. and % Al. 2. O. 3. was studied for preconcentration of iron values adopting Jigging and Dry High ...
Keywords: Beneficiation, BHQ, Gravity concentration, Magnetic separation, Reverse flotation. INTRODUCTION India''s iron ore reserve is around 25,249 million tonnes (MT) apart from Banded Hematite Quartzite (BHQ) and Banded Hematite Jasper (BHJ) and occupies sixth position in the world iron ore reserves.[1, 2] Although India is blessed with ...
· Banded Hematite Jasper (BHJ) deposits are abundant reserves available in India and are currently not being used for production purposes due to its high Silica content. Iron Ore Scenario in India India possesses hematite resources of 11,426 million tons of which 6,025 million tons are reserves and 5,401 million tons are remaining resources (Indian Mineral Year Book, 2008).
A flotation process has been developed to treat one such ore, namely banded hematite quartzite (BHQ) containing % Fe and % SiO2, by using oleic acid, methyl isobutyl carbinol (MIBC), and sodium silie as the collector, frother ...
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 . In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small amounts.
