Samarco Mineração owns Germano operations (comprises the Alegria mines), in the cities of Mariana and Ouro Preto (MG), where Samarco extracts and processes the ore; and Ubu (Anchieta - ES), where Samarco maintains industrial (pelletizing) and port activities.

After five years of suspended operations due to the failure of the Fundão dam, Samarco resumed operations at the Germano complex and the Ubu unit in December 2020.

Deposit Type

  • Banded iron formation

Summary:

Itabirite ore type.

Samarco’s Alegria mine complex and Germano mine, located in Mariana, Minas Gerais, is in the same region as Vale's Southeastern System - Quadrilatero Femfero (Iron Quadrangle).

Ore reserves with high ratios of itabirite ore relative to hematite ore type. Itabirite ore has iron grade of 35-60%.

The Quadrilátero Ferrífero (QF) comprises an area of about 7000 km2 and hosts one of the largest concentrations of lateritic iron-ore deposits in the world. The QF is located in central Minas Gerais state, southeastern region of Brazil (Dorr, 1965). The QF has a quadrangular shape due to the dome and basin structures of the Minas Supergroup. Most of the iron ore in the QF are hosted in the oxidized, metamorphosed and heterogeneously deformed Banded Iron Formations (BIFs) of the Cauê Formation, the so-called itabirites. The BIFs are altered sedimentary deposits with laminated rocks formed by alternating layers of silica and hematite magnetite, as well as carbonates and iron silicates.

The Quadrilátero Ferrífero is located at the southeastern border of the São Francisco Craton, southeastern Brazil. According to Alkmim and Marshak (1998) the most important lithostratigraphic units of the Quadrilátero Ferrífero are: (1) the Archean crystalline basement, (2) the Rio das Velhas Supergroup, (3) the Minas Supergroup, (4) the Post-Minas Intrusives and (5) the Itacolomi Group.

Basement crystalline rocks include a gneiss/ ........
