2019年1月31日 · Banded hematite quartzite (BHQ) and banded hematite jasper (BHJ) ores are low-grade iron ores with high silica and alumina content, found in the Indian subcontinent. BHQ ores generally contain 35–38% Fe, 42–45% SiO 2, and 0.5–2.5% Al 2 O 3, while BHJ ores contain 40–45% Fe, 38–40% SiO 2, and 1–1.5% Al 2 O 3 [1, 2, 3].

2019年1月31日 · Banded hematite quartzite (BHQ) and banded hematite jasper (BHJ) ores represent a promising potential iron ore resource in the near future. The hematite and quartz in BHQ and...

2022年9月1日 · The banded hematite jasper (BHJ) ore beneficiation/processing investigations are mainly confined to carbothermal reduction (Rayapudi et al., 2020). These studies report that carbon-based reductants such as coke/charcoal/coal contributes to …

2021年1月1日 · High alumina & silica content of Indian Iron ore resources require suitable beneficiation techniques to produce quality raw material for steel manufacturing. Banded Hematite Jasper (BHJ) reserves are abundantly available in India but not considered as an ore of Iron for production purposes due to its high Silica content and complex mineralogy.

2019年10月25日 · Detailed characterization and beneficiation of the banded hematite jasper (BHJ) from Joda area, eastern India, was studied. The main purpose of this study is to produce a pellet feed from the BHJ ore using a simple flow sheet. The feed sample contained total Fe (35.31%), SiO2 (48.73%), Al2O3 (0.58%) and loss of ignition (1.02%).

2018年6月19日 · A comprehensive utilization of BHJ ore was investigated using reduction roasting and smelting method. The influence of temperature, time, coal size, ore size and coal-to-feed ratio on reduction roasting of BHJ ore was established. An innovative approach towards the substitution of silica resource in ferrosilicon production was also proposed.

2018年2月1日 · Due to high demand of good quality iron ores and rapid depletion of high-grade ores, it has necessitated to emphasize on beneficiation of lean ores like banded hematite jasper (BHJ) and banded...

2019年12月17日 · Here, a comparative analysis of the reduction performances of a low-grade Banded Hematite Jasper (BHJ) ore has been done between the conventional and microwave heating routes. The...

Iron ore resources have their own peculiar characteristics requiring suitable beneficiation process to produce quality raw material. Banded Hematite Jasper (BHJ) reserves are abundantly available in India but currently not being used for production purposes due to its high Silica content.

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. 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).
