Summary:

The Andrade mine (pi. 1, No. 1) 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.


Mining Methods

  • Truck & Shovel / Loader


Summary:

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.


Crushing and Grinding


Processing


Summary:

The ore is delivered to a crushing plant, consisting of a 90 by 120 cm jaw crusher and two AKBED cone crushers. The ore is crushed to 8 cm and separated by screening into a <24-mm fraction and into a >24- to 55-mm fraction; the ore is then stored in bins from which it is discharged into railroad cars and hauled to Monlevade.
