en.Wedoany.com Reported - Vale has completed the decommissioning of the B7A tailings dam at the Águas Claras Mine in Nova Lima, Minas Gerais. The structure no longer retains water or sediment and no longer functions as a tailings dam. This initiative is part of the Mine Environmental Closure Plan (Plano Ambiental de Fechamento de Mina, PAFEM), which outlines solutions and timelines for the safe closure of mine facilities and their reintegration with the environment. Angélica Silva, Vale's Geotechnical General Manager, stated that this is another significant achievement, underscoring Vale's commitment to the safety of people and the environment.

As part of advancing the decommissioning of structures at the Águas Claras Mine, Vale has initiated engineering work on the B6 tailings dam, expected to be completed in the second half of 2027, aiming to achieve the same goal as B7A—ensuring the structure no longer functions as a tailings dam. At the Águas Claras Mine, the decommissioning of the 8B tailings dam and the auxiliary cofferdam of Tailings Dam No. 5 has been completed, while the 7B and 5 MAC structures are in the project design phase. These structures have been deactivated and were built in a single stage or with downstream raising. Until the engineering work is completed, these tailings dams will continue to undergo regular inspections and be monitored 24/7 by the company's Geotechnical Monitoring Center (Centro de Monitoramento Geotécnico, CMG).
