From mine to the port

It all starts at the Germano Complex, in the municipalities of Mariana and Ouro Preto, in Minas Gerais, where iron ore is extracted and processed. In the form of slurry, it is transported via pipelines, which cross 25 municipalities to reach the Ubu Complex, in Anchieta, Espírito Santo. In this unit, the ore goes through the pelletizing process and, finally, it is shipped from its own port ...
