Mining in Brazil

Mining in Brazil is centered on the extraction of iron (the second largest global iron ore exporter), copper, gold, aluminum (bauxite-one of the 5 biggest world's productors), manganese (one of the 5 biggest world's productors), tin (one of the biggest world's productors), niobium (concentrates 98% of the known niobium reserves in the world), and nickel. About gemstones, Brazil is the world's largest producer of amethyst, topaz, agate and is a big producer of tourmaline, emerald, aquamarine, garnet and opal.

History

* Discovery of first gold rush in 1690s, gold discoveries made in streams not far from present day city of Belo Horizonte.
* In 1729 diamonds were discovered in the same area. This started a diamond rush.
* By 1760 nearly half of the world's gold was from Brazil.
* In the early 18th century nearly 400,000 Portuguese immigrants came to mine in southern Brazil.
* Over half a million African slaves were shipped to work in the gold mines.
*The Gongo Soco gold mine, operated by the Imperial Brazilian Mining Association of Cornwall using skilled Cornish miners and unskilled slaves, produced over of gold between 1826 and 1856.

Metallic ores

In 2016, metallic ores totaled close to 77% of the total value of Brazilian mineral production that was sold. Eight elements totaled 98.6% of the value: aluminum, copper, tin, iron, manganese, niobium, nickel and gold. The biggest Brazilian highlight is in iron, which has the majority of the participation, whose production is mostly carried out in the states of Minas Gerais and Pará. According to the National Department of Mineral Production (DNPM), in 2011 there were 8,870 mining companies in the country, and in the Southeast Region, this number reached 3,609, about 40% of the total. In the Southeast region, iron ore, gold, manganese and bauxite stand out in the Quadrilátero Ferrífero; niobium and phosphate in Araxá; gems, in Governador Valadares; and graphite, in Salto da Divisa, all in the state of Minas Gerais; in addition to aggregates, in São Paulo and Rio de Janeiro, and ornamental rocks, in Espírito Santo. The mining sector's revenue in Brazil was R$ 153.4 billion in 2019. Exports were U$ 32.5 billion. The country's iron ore production was 410 million tons in 2019. Brazil is the second largest global iron ore exporter and has the second position in the reserve ranking: under Brazilian soil there are at least 29 billion tons . The largest reserves are currently in the states of Minas Gerais and Pará. According to data from 2013, Minas Gerais is the largest Brazilian mining state. With mining activity in more than 250 municipalities, and more than 300 mines in operation, the state has 40 of the 100 largest mines in Brazil. In addition, of the 10 largest mining municipalities, seven are in Minas, with Itabira being the largest in the country. It is also responsible for approximately 53% of the Brazilian production of metallic minerals and 29% of the total minerals, in addition to extracting over 160 million tons/year of iron ore. Vale S.A. is the main company active in the production of iron ore in the state. The state is the largest employer in the mineral activity (53,791 workers in 2011). São Paulo, the second largest employer, had 19 thousand employees in the sector this year.

In 2017, in the Southeast Region, the numbers were as follows: Minas Gerais was the country's largest producer of iron (277 million tons at a value of R$ 37.2 billion), gold (29.3 tons at a value of R$ 3.6 billion), zinc (400 thousand tons at a value of R$ 351 million) and niobium (in the form of pyrochlorine) (131 thousand tons at a value of R$ 254 million). In addition, Minas was the 2nd largest producer of aluminum (bauxite) (1.47 million tons at a value of R$ 105 million), 3rd of manganese (296 thousand tons at a value of R$ 32 million) and 5º of tin (206 tons at a value of R$ 4.7 million). Minas Gerais had 47.19% of the value of mineral production traded in Brazil, with R$ 41.7 billion.Anuário Mineral Brasileiro 2018

In vanadium, it produced 358 thousand tons, at a value of R$ 91 million.

Coal

Santa Catarina is the largest coal producer in Brazil, mainly in the city of Criciúma and surroundings. The production of crude mineral coal in Brazil was 13.6 million tons in 2007. Santa Catarina produced 8.7 Mt (million tons); Rio Grande do Sul, 4.5 Mt; and Paraná, 0.4 Mt. Despite the extraction of mineral coal in Brazil, the country still needs to import about 50% of the coal consumed, as the coal produced in the country is of low quality, as it has a lower concentration of carbon. Among the countries that supply Brazil with mineral coal is South Africa, USA and Australia. Mineral coal in Brazil supplies, in particular, thermoelectric plants that consume about 85% of production. The cement industry in the country, on the other hand, is supplied with approximately 6% of this coal, leaving 4% for the production of cellulose paper and only 5% in the food, ceramics and grains industries. Brazil has reserves of peat, lignite and hard coal. Coal totals 32 billion tons of reserves and is mainly in Rio Grande do Sul (89.25% of the total), followed by Santa Catarina (10.41%). The Candiota Deposit (in Rio Grande do Sul) alone has 38% of all national coal. As it's a coal of inferior quality, it's used only in the generation of thermoelectric energy and at the site of the deposit. The oil crisis in the 1970s led the Brazilian government to create the Energy Mobilization Plan, with intense research to discover new coal reserves. The Geological Survey of Brazil, through works carried out in Rio Grande do Sul and Santa Catarina, greatly increased the reserves of coal previously known, between 1970 and 1986 (mainly between 1978 and 1983). Good quality coal, suitable for use in metallurgy and in large volume (seven billion tons), was then discovered in several deposits in Rio Grande do Sul (Morungava, Chico Lomã, Santa Teresinha), but at relatively great depths (up to 1,200 m), which has hindered its use until now. In 2011, coal accounted for only 5.6% of the energy consumed in Brazil, but it is an important strategic source, which can be activated when, for example, the water levels in the dams are very low, reducing excessively the supply of water. hydroelectric power. This happened in 2013, when several thermoelectric plants were then shut down, thus maintaining the necessary supply, albeit at a higher cost.

Gemstones

Brazil is the world's largest producer of agate. Rio Grande do Sul is the largest producer, with local extraction since 1830. There is also extraction in Minas Gerais and Bahia. In aquamarine, Minas Gerias produces the most valuable stones in the world. This gem is also produced in Espírito Santo, Rio Grande do Norte, Ceará, Alagoas and Paraíba. The largest world producer of amethyst is Brazil, in the states of Rio Grande do Sul mainly, and secondarily, in Bahia. The largest producer of amethyst in Brazil is the city of Ametista do Sul, in Rio Grande do Sul. This stone was very rare and expensive worldwide, until the discovery of large deposits in Brazil, causing its value to drop considerably. Algumas Gemas Clássicas

Brazil was the largest producer of diamond in the world from 1730 to 1870. Mining first occurred in the Serra da Canastra, Diamantina region, and then, in 1850, in Bahia, even dropping the price of stone worldwide due excess production. Today, Brazil produces close to 1 million carats a year, mainly in the State of Minas Gerais, but also in Mato Grosso, Mato Grosso do Sul, Bahia, Paraná and Roraima. Virtually all states in the country have diamonds.

Regarding emerald, the largest producers in the world are: Colombia, Zambia, Zimbabwe, Tanzania, Madagascar and Brazil. It is produced in the states of Goiás, Bahia and Minas Gerais. In garnet, Brazil is not one of the largest producers, but there is extraction in Minas Gerais, Espírito Santo, Bahia, Paraíba, Ceará, Rondônia and Rio Grande do Norte . In Brazil there are also some jasper in Minas Gerais, Mato Grosso, Paraná and Rio Grande do Sul. Another rare stone to be found in Brazil is opal, but there are deposits in Piauí, Bahia, Ceará and in Rio Grande do Sul. Ruby is also rare in Brazil, being found in Bahia and Santa Catarina. Sapphire is also scarce in Brazil, but can be found in Mato Grosso, Goiás, Santa Catarina and Minas Gerais. In the topaz, Brazil has the most valuable variety in the world, the imperial topaz, only produced in Ouro Preto-MG. In addition, the country is the world's top producer of topaz. It is also among the world's largest producers of tourmaline, in the states of Minas Gerais, Ceará, Goiás and Bahia. Brazil produces the rarest and most expensive variety of tourmaline in the world, Paraíba tourmaline, which, in addition to Paraíba, is only found in three other places in the world: in Brazil (at the state of Rio Grande do Norte) and Africa (at Nigeria and Mozambique). But none of them offers a higher quality stone than São José da Batalha. In turquoise, there is only a small production in Bahia.Região colombiana vive 'febre das esmeraldas'
