Oxidised pellets have become an indispensable high-quality charge for blast furnaces. Nevertheless, high-quality pellet feeds are becoming scarcer and scarcer. To broaden the range of sources of pellet feeds and reduce the production cost of pellets, more steel mills are predicted to use coarse iron ore fines with a relatively low iron grade and …
Brazil is one of the largest iron ore producers in the world; the Quadrilátero Ferrífero region (Iron Ore Quadrangle) is responsible for around 65% of the Brazilian iron ore supply (Dauce et al. 2019; Vilaça et al. 2022).This has led to the generation of enormous amounts of iron ore tailings (IOT) derived from the extraction and …
immediately before flotation. In Brazil, the generation of iron ore tailings (coarse or fine tailing) is estimated at 20-40% by the weight of the total iron ore mining.13,18 1.2. Generation iron ore tailings (IOT) and environmental problems Iron mining is of great importance for economic development, however, it generates a huge extension of
The transition zone between the Archean blocks, Jequié and Itabuna-Salvador-Curaçá, in the county of Laje, Bahia, Brazil, is potentially important for iron ore deposits of economic interest.
The interpretation of the data of the geophysical methods allowed to delineate two zones in the area, both located at magnetic anomalies, gravity highs and relatively conductive parts. The two zones have a high potential for iron ore, because they present significant and correlated anomalies. Key words: Gravity, iron ore, magnetic, VLF-EM.

Purpose. To improve of the sub-level caving mining methods during mining of deposits of high-grade iron ores by applying a rational mode and intensifying the ore drawing.
In Brazil, the two most important iron ore types are hematite rich and itabirite (banded iron formations (BIF)). Hematite rich type is extracted mainly in the state of Pará and has an average iron content …
We intend to sustainably develop Bahia's iron ore resources as Brazil's new green iron and steel province, using renewable energy and green hydrogen. We intend to operate with net-zero carbon emissions and to deliver net-positive outcomes for the environment and our communities .
Currently, China is the largest buyer of Brazilian iron ore, see Figure 1, (Montilha & Botter, 2015). Iron ore in Brazil is mainly mined in three areas: Quadrilatero Central (1), Maciço do Urucum (2) and Serra dos Carajás (3), see Figure 7. Quadrilatero Central is located at the Center-South region of the State of Minas Gerais.
