The beneficiation of low-grade iron ores is a key research and development topic in the mineral processing industry. The gradual exhaustion of high-grade iron ore reserves, and rising consumer iron and steel demand globally necessitate efficient low-quality iron ore beneficiation to meet steelmaking quality requirements. This comprehensive review explores …
Laterite (sensu lato) is a soil formation in which primary textures are destroyed and is underlain by a pallid zone showing the preservation of chert and the depletion, not enrichment, of iron ...

Most world-class high-grade (60 - 67 wt per cent Fe) hematite iron ore deposits are the product of enrichment of Precambrian iron-formations but processes responsible for enrichment are still unclear.
The Moloundou iron ore is classified as high-grade iron ore since it contains Fe grade ˃ 65 wt and minor amount of deleterious elements (e.g., SiO2, Al2O3, and P2O5).
Iron ore deposits mined in Malaysia consist of high-grade hematite-magnetite ore containing more than 60% of Fe (Lee and Abdoul-Fatah 2002). The ore are typically removed in benches that vary from ...
The characterization and upgrading of low-grade iron ore from Sungai Petani, Kedah, face significant challenges due to the presence of gangue minerals such as silica (Si), alumina (Al), and … Expand

Description and properties of common iron ore minerals. Iron ore minerals are rocks or minerals that contain iron in concentrations high enough to be economically extracted. Common iron ore minerals include: Hematite (Fe2O3): Hematite is the most abundant and important iron ore mineral. It is typically steel-gray to black in color and has a metallic luster.
In general, the composition of iron ore typically consist major oxides of Fe 2 O 3, SiO 2, and TiO 2 . Iron ore deposits mined in Malaysia consist of high-grade hematite …

The Brockman Iron Formation in this province is the most significant host for high-grade hematite iron ore deposits. Magnetite is an iron oxide mineral that is generally black and highly magnetic. The latter property aids in the beneficiation of magnetite ores. Magnetite contains 72.4% Fe by molecular weight, which is higher than hematite, but ...

A test pit excavation of a 1 × 1 meter area to a depth of 20 cm yielded tuyere fragments, iron ore, raw iron, and iron slag. The sources of ore are found in small hills and river cliffs in Karang Besi and Bukit Batu Besi in Tanjung Beringin Village. The Dayak Tomun people refer to iron ore as maurau, which means melting iron stone.

The base of the furnace IV consists of soil and bricks measuring about 110 cm long and about 90 cm wide. Therefore the shape of the furnace structure at this site ...
Artifacts of iron ore that are still in-situ and associated with either the bases of furnace, iron ingot, iron slag and tuyere will be selected to undergo XRF analysis.
The results of the iron ore survey were then subjected to scientific analysis to compare the mineral composition with the findings of iron ore at the iron smelting site.
"The society was so advanced that they possessed both knowledge and capabilities to mine and smelt iron. This is particularly remarkable because iron melts at very high temperatures, around 1,600° Celsius," Siti points out while …
