The recovery of the Paraopeba river and its biodiversity is one of the most
important propositions of our work. We have short, medium, and long-term measures underway. In
2019, we implemented a series of measures that prevented sediment from flowing into the river
and contained the tailings.
After containing the tailings and avoiding contamination of the river, we
installed two river water treatment plants (ETAFs, Estações de Tratamento de Água Fluvial) that,
by July 2020, returned more than 17 billion liters of water to the river – on average five times
cleaner than the limit established by the National Council for the Environment (Conama, Conselho
Nacional de Meio Ambiente).
Tailings removal retake
The removal stopped in March, because of the coronavirus pandemic, and retaked in
August. Up to now, we have already handled approximately 1,8 million m³, which correspondes to
20% of the total.
Dam Safety
B6 Dam, one of Córrego do Feijão remnant geotechinical structures, has received
positivity Stability Condition Declaration (DCE) and was moved from level 1 of Mining Dam
Emergency Action Plan (PAEBM) having returned to level 0, which attests stability conditions and
dan safety.
