Report summary
Miguel Burnier is a closed surface mine owned by Gerdau located in the Quadrilátero Ferrífero (QF) region of Minas Gerais state, Brazil, approximately 85 kilometres south of the city of Belo Horizonte. The operation used to produce a concentrate product which was typically transferred to Gerdau's nearby Ouro Branco steel mill or, to a lesser extent, sold into the seaborne export market. Miguel Burnier's mining operations were closed at the end of 2015 due to weak iron ore and steel market conditions. Still, the mine's processing facilities remain operational handling ore trucked from Várzea do Lopes.
