The Brazilian unit of steel group ArcelorMittal moved 30 families from their houses near its Serra Azul mine in the town of Itatiaiuçu, Minas Gerais state, as a precautionary action after it ran a new risk evaluation of a dam close to the mine. The company said on Thursday that there was no change in the status of the tailings dam that was idled in 2012, but decided to transfer the families after updating its evaluation of potential risk areas in the case of an accident with the structure.
