Mining

Pedra de Ferro

Pedra de Ferro is the most important iron mining project under development in Bahia. Implemented by BAMIN, the project includes extraction and processing of ore from the Pedra de Ferro Mine and logistical solutions that include rail and sea transport. The BAMIN project stands out for its high degree of innovation, one of the company's essential values, which guarantees processes of maximum efficiency and excellent results, in addition to sophisticated environmental and operational safety controls.

BAMIN will sustainably produce two types of minerals - Hematite and Itabirite, both accepted in tests on the international market - which extend over an area of 8,243.25 hectares, maintaining an area of Legal Reserve and Forest Compensation of 4,047.0215 hectares.

Hematite has a high purity content (about 65% Iron Ore), which allows dry processing, thus reducing water consumption in the process. With different characteristics, itabirite is extracted in greater depth and is separated by layers of sand, which requires the use of water in its processing.

Ensuring the preservation of water resources is one of the main concerns of BAMIN, which will collect water from the Rio São Francisco (São Francisco River). For this reason, the entire process is again anchored in innovation, with modern treatment methods for reusing a large part of the water in the processing of the ore and which will even increase the water supply in the region, by returning another part of the water, after treated and cleaned, in stretches of the Córrego da Cachoeira (Cachoeira Stream) and part of Rio Grande. The same rigor and care, the company will apply to the tailings dam of the beneficiation process. In addition to the implementation of the most modern construction standards for this type of equipment, the dam will have, among other technologies, more than 150 Manual and Automatic Monitoring and Control Instruments.

Disposal of tailings

Our project licensed by INEMA provides for the construction of a tailings dam downstream with a stability and safety coefficient of 2.24, well above the score of 1.5 required by Brazilian law and international practices. Always seeking to guarantee maximum safety, BAMIN has been researching the incorporation of tailings filtering facilities in the last two years, significantly increasing water recovery, converting the tailings dam into a dry pile facility and, therefore, implementing operational safety of state-of-the-art tailings. In addition to the safety aspects of the tailings filtration facilities, water recovery of more than 90% is significantly reducing water usage.

The completion of basic engineering is scheduled for July 2021 and will be presented to INEMA and ANM, to start the project and update the implantation license.
