Brumadinho disaster in Minas Gerais, Brazil, in 2019. In the 1990s it was estimated that some 500,000 miners were working claims across the region. Legal and illegal gold mines, many located in or adjacent to native reserves and national parks, placed additional pressure on land.

2008/8/12If managers chose to make iron for conversion into steel, their blasts furnaces were attached to large mills where the pig iron could be transferred, while still molten, directly to steel furnaces. Republic Steel in Gadsden At the beginning of the twentieth century, there was large-scale consolidation within the American iron and steel industry.
Usinas Siderurgicas de Minas Gerais SA USIMINAS and its subsidiaries, jointly-controlled companies and affiliates are engaged in steelworks and other related activities. The Company's activities include iron ore extraction, steel transformation, production of capital goods and logistics.
The EFVM moves iron ore from Minas Gerais main southeastern mines to Vitoria port, where Vale operates the Tubarao complex of pellet plants and export terminals. Coking coal comes into Vitoria mainly from the US and Australia for onward delivery to Minas Gerais, Ipatinga-based Usiminas and Ouro Branco-based Gerdau Acominas integrated steel plants.
Minas Gerais is the second largest producer of cast steel, iron, aluminum, bronze and brass, with an installed capacity of 2 million tons/year. With approximately 400 companies, the state has 30% of the Brazilian production, especially in the central-west region (Divinpolis, Cludio and Itana), with an LPA Foundry with 120 companies.

Iron ore grade reduction in Brazilian deposits, mainly in the Iron Quadrangle, results in the need for concentration in order to meet the specifications of the steel industry. This context applies for a large number of mines that nowadays operate with Hematite or high grade Itabirite and who in the near future, will have to beneficiate low grade and compact Itabirite.

Vale's Minas Itabiritos mining site in the state of Minas Gerais, Brazil, hosts the world's third biggest iron ore mining operation. The proven and probable ore reserves of Minas Itabirito, which comprises four mines, Segredo, Joao Pereira, Sapecado, and Galinheiro, were 2.78 billion tonnes at the end of 2012.

18 and the State of Minas Gerais (CODEMIG 2010; Figure 1). It has a long and important mining 19 history, containing approximately 75% of Brazil's measured iron ore reserve, half of which is 20 graded above 60% iron content (Gurmendi 2011). The
The Iron Quadrangle (Portuguese: Quadriltero Ferrfero) is a mineral-rich region covering about 7,000 square kilometres (2,700 sq mi) in the central-southern part of the Brazilian state Minas Gerais.The area is known for its extensive deposits of gold, diamonds, and iron ore, being the source of approximately 40% of all gold produced in Brazil between the years 1500 and 2000.
The complex, at full capacity, was constructed to produce 1 million tons of crude steel per year, of which 700,000 t used to manufacture 600,000 tons of seamless steel pipes with Premium connections, a product with high added value. The plant production is
Smarter steels depend on high-quality raw materials. As one of the world's leading producers of iron ore, we supply nearly half of our own iron ore needs and provide the types of coal that are essential to steelmaking. Our mining assets provide supply security and quality for our own operations, and a source of high-value raw materials for our customers.
However, in the country's largest iron ore mining region, the Quadriltero Ferrfero (QF) in Minas Gerais (located outside the Amazon forest), mining companies reduced off-lease deforestation by conserving land adjacent to leases 43, 44.
