📚 Free e-book with summaries of the most common topics in Humanities, Languages ​​and Writing: http://bit.ly/2XkPac8 The very old rock formation favors the wide variety of mineral resources in Brazil. Some of these minerals found in Brazil, in addition to being used by the country's own industries, are destined for export. Want to know more about this subject?

Video description: 00:00 - Hello, my little miners! \o/ Brazilian mineral resources, let's start by differentiating between mineral and ore. What is a mineral? An inorganic chemical compound found naturally in nature. Ore is this compound that has commercial value, like water and oil, for example. 00:50 - To talk about mineral resources in Brazil, we need to talk about Brazilian geological structures. Geological structures are those that are below the relief. Since Brazil is a region where tectonic plates do not meet, it does not have such recent structures. Here we have two types of structures: crystalline shields and sedimentary basins. Crystalline shields have metallic and semi-metallic minerals. And in the sedimentary basins we will find non-metallic minerals. 00:56 - Let's start by talking about the Iron Quadrangle, a very important subject, since we are talking about mining in Minas Gerais. Here it is essential to mention the tragedies of Mariana and Brumadinho. Remember that there is still the possibility of other tragedies happening due to the dams built in these regions. So since Colonial Brazil, the Iron Quadrangle region has been the main region for mineral exploration in Brazil. What can be found there? Gold (in the Colonial period, which generated a very intense process of occupation with people going in search of gold); and today we have Iron, Bauxite, Manganese and Copper. Iron stands out, as it is one of the main products of this region. 2:43 - Which companies stand out when it comes to this mineral exploration? Vale and Companhia Siderúrgica Nacional (CSN). Remember that Vale was once a government company (at the time called Vale do Rio Doce) and today it is a private company responsible for the most recent tragedies related to mining waste in Brazil. We also have the Serra dos Carajás! We left the Southeast and went to the North of the country, more specifically to Pará. In the 1960s, this region began to attract a contingent of people for exploration. What minerals exist there? Iron, Copper, Gold, Manganese, Bauxite, Silver, Nickel, Chromium and Tungsten. 3:42 - The Urucum Massif, there in Mato Grosso do Sul, does not have an easy drainage route, which makes mining in the region difficult, since the minerals are very heavy. It is necessary to have railways or waterways to facilitate the mining process. Iron and Manganese are found in this region ;) 4:37 - Brazil will also explore other minerals, such as coal, in the south of Santa Catarina and Rio Grande do Sul. The problem with Brazilian coal is its quality. The quality of coal is measured by the amount of heat it generates. The problem with Brazilian coal is that it generates a lot of waste, so a lot of heat is lost in the process (it generates a lot of ash). 5:39 - Sea salt, which we consume, is also a mineral extracted from the salt mines of Rio Grande do Norte and Rio de Janeiro, mainly. Oil is also explored in the Campos Basin and Santos Basin. Watch the class on OPEC to learn more about oil, don't fly ;) 7:37 - And Uranium, which is extremely important for the generation of nuclear energy and in the production of weapons. Brazil is the largest producer of Uranium and also refines it, which has even led to accusations that the country is processing Uranium for military/war purposes! 8:27 - That's it for today, folks \o/ Don't forget to like and subscribe to the channel so you don't miss the next classes.
