Samarco Mineração S.A. is a Brazilian company engaged in the mining, beneficiation, pelletizing and export of iron ore. The firm has four pellet plants in Anquieta municipality, in Brazil's Espírito Santo state, as well as three concentrators in its Germano plant in Minas Gerais state. It also has a port terminal in Ponta Ubu, Espírito Santo, sales offices in Belo Horizonte and Victoria, and two international offices in Amsterdam and Hong Kong. Its yearly production capacity reaches 30.5Mt. The company is owned equally by Vale and BHP Billiton. Samarco Mineração was founded in 1977 and is based in Belo Horizonte in Minas Gerais state. On November 5 2015, Samarco's Fundão tailings dam – used to hold water and discarded minerals from a nearby iron-ore mine – collapsed and destroyed the village of Bento Rodrigues in the Brazilian state of Minas Gerais. The dam released an avalanche of mud and mine waste that left 19 people dead and numerous homeless, as well as polluting hundreds of miles of rivers in southeast Rio Doce basin. This accident has been described by Brazilian authorities as the biggest environmental disaster in the country's history. Samarco's operations were shut down indefinitely after the event. On March 2 2016, Samarco and its shareholders entered into an agreement with the Brazilian authorities for the restoration of the environment and communities affected by the dam failure.
