Midwester integrated operation includes Urucum and Corumbá mines and two plants located in the city of Corumbá, State of Mato Grosso do Sul.

In April 2022, Vale entered into a binding agreement with J&F Mineração Ltda. (“J&F”) for the sale of of all the shares issued by Mineração Corumbaense Reunida S.A., Mineração Mato Grosso S.A., International Iron Company, Inc. and Transbarge Navegación Sociedad Anónima, which hold Vale's iron ore, manganese ore and logistics assets in the Midwestern System. The agreed enterprise value of the transaction is approximately US$1.2 billion for the assets. At closing, we expect to receive approximately US$150 million, in addition to transferring to J&F the obligations related to the take-or-pay logistics contracts, subject to the consent of the applicable counterparties, and other liabilities existing in the transferred assets.

Deposit Type

  • Banded iron formation


Summary:

Hematite ore type, which generates lump ore predominantly. Iron grade of 62% on average. High-grade manganese ore (an average content of 46% manganese grade).

The manganese and iron deposits of the Morro do Uruclun are located about 25 kilometers south of the city of Corumba, Mato Grosso, Brazil.

The deposits of both manganese and iron occur in the Jacadigo series, of unknown but probably late pre-Cambrian or early Paleozoic age. This has been subdivided into the Urucum, the Corrego das Pedras, and the Band' Alta formations. The Urucum formation, between 400 and 500-meters thick, consists of continental deposits of arkose and conglomerate. It grades upward into the Corrego das Pedras formation, about 95 meters thick, in which ferruginous arkose at the base grades upward into ferruginous sandstone and ferruginous jasper. Above the Corrego daa Pedras formation is the Band' Alta formation, at least 300 meters in thickness, which contains the deposits of manganese and iron. At the base of the Band' Alta is a widespread bed of the manganese oxide cryptomelane. This is overlain by banded siliceous hematite, which makes up the greater part of the formation but is interbedded, about 40 meters or more above the base, with other lenticular beds or cryptomelnns, and, higher in the section, with lenticular beds of clastic rocks, including siltstone, sandstone, and, rarely, conglomerate. The formation is cut off at the top by an erosion surface.

Mining Methods

  • Truck & Shovel / Loader
  • Room-and-pillar


Summary:

Midwestern System is located at State of Mato Grosso do Sul in Brazil and includes Urucum underground mine with on-site beneficiation plant and Corumba open pit mine with beneficiation plant.

Corumba open pit mining operations is conducted via truck and shovel method to extracting hematite ore. Predominantly production is represented by lump ore with an iron average grade of 62%.

Urucum underground mine is employed Room and pillar mining method to extract high and medium grade oxide ores with an average content of 46% manganese grade.
