EVENT – The Social Cost of Tailings Management – Talk by Angelica Amanda Andrade (Thu., 28 July 2022)

Who is Angelica Amanda Andrade?
Born and raised in the small town of Brumadinho, Brazil, I am an English teacher who had my life devastated on January 25, 2019, when the B1 tailings dam in one of Vale’s mining complexes collapsed, creating a massive wave of toxic mud that destroyed and killed everything in its way.
My sister, Natalia, who worked as an administrative analyst for Vale, was having lunch at the cafeteria at that time with at least another 100 employees. The administrative sector, which included the cafeteria, had been built below the dam and when it burst the sirens, intended to alert the people around and give them a chance to escape, didn’t work.
Few who were there could escape, as they were taken by surprise. Sadly, my sister wasn’t among the survivors.

Probability of Tailings Dam Failure Using ALARP
In the paper we use an anonymized case to show how a dam’s probability of failure and risks evolve with its raising. In a second step we explicitly discuss the search for the ALARP risk mitigation level for a specific dam elevation.
