Mine Life38 years (as of Jan 1, 2015)
Samarco comprises a mine and three concentrators located in the Brazilian state of Minas Gerais, four pellet plants and a port located in Anchieta in the state of Espírito Santo.

In December 2020, Samarco commenced the gradual resumption of its operations, with the integrated restart of iron ore extraction and beneficiation in the Germano complex, located in Mariana, state of Minas Gerais, and pelletizing at the Ubu complex, located in Anchieta, state of Espirito Santo. Samarco’s operations are resuming with approximately 7 to 8 Mtpy production capacity, with the use of one of three concentrators to beneficiate iron ore in the Germano complex and one of four pellet plants in the Ubu complex, representing 26% of Samarco’s productive capacity. The integrated restart of operations occurs after extensive commissioning tests after the five-year halt.

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 (Fig. 1). 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 ........
