The Andrade mine is on the northeast flank of the Pico do Andrade 8 kilometers northwest of Monlevade. This mine is linked to the Usina Monlevade by a 10-kilometer meter-gage electrified railroad.The Andrade deposit is on the Fazenda de Andrade, which along with several smaller fazendas was acquired by CSBM in 1921.

The ore occurs in the troughs of the syncline and for more than 1,000 meters along the east flank. The ore body as it crops out or is exposed in the opencut mining perations is arcuate, concave to the northeast.

The distribution of the various types of ore and itabirite is highly irregular, and it was not feasible to map them separately. Not uncommonly, alternations of equigranular and schistose material occur in bands, lenses, and irregular forms from a few tenths of a meter to several meters is size. The median length of the ore body is approximately 2,100 meters, extending from the Pico do Andrade slightly north of east for about 1,500 meters and from the peak to the north about 600 meters. The average stratigraphic thickness is about 100 meters.

Both the Andrade and Serra Azul mines are located in the Iron Quadrangle (Quadrilátero Ferrífero), a widely-explored and mined region. The mineralization occurs as Itabirites, banded hematite-silica rocks, with varying weathering degrees. While the Serra Azul ore reserve estimates are constituted of rich friable Itabirites requiring some beneficiation, the Andrade ore reserve estimates are dominated by directly shippable hematite ore.

ArcelorMittal Brasil holds mineral rights of over 2,421 hectares located in the Iron Quadrangle (Quadrilátero Ferrífero), in the Andrade Mine area, a widely-explored and mined region located approximately 80 kilometers east of Belo Horizonte in the Minas Gerais State of Brazil. ArcelorMittal’s operations control all of the mineral rights and surface rights needed to mine and process its estimated 2020 iron ore reserves, dominated by directly shippable hematite ore.

The deposit is mined by open pit mining method with a series of benches extending from the top to the base of the Pico do Andrade. The working faces of the benches are 20 meters high. The benches are linked to each other and to the crushing plant by roads that have a maximum grade of 8 percent.

An increase of the crushing and screening facility production capacity to 3.5 million tonnes per year of sinter feed was completed in 2012. In 2018, Andrade started development of a concentration plant to improve the quality of the sinter feed to the Monlevade plant and positively impact costs and life span. This plant commenced production in early 2020 and concentrates the itabirite ores, enabling mixing with the higher grade hematite ores.
