#0183;#32;The Valeowned Carajas mine in the state of Para in Northern Brazil is the worlds biggest iron ore mine holding billion tonnes of proven and probable reserves as of December 2012. Carajas is an open pit mining operation targeting the Serra Norte, Serra Sul, and the Serra Leste iron ore deposits in the Caraj#225;s District.
Fig 1 A typical open pit iron ore mine. On the basis of mining methods, iron ore mining can be broadly divided into two categories namely manual mining and mechanized mining. Large iron ore mines are mechanized mines while manual mining methods are employed in the small mines. Manual mining method is normally limited to float ores.

This image of the Caraj#225;s Iron Ore Mine was taken by the Advanced Land Imager on NASAs EO1 satellite on July 26, 2009. Terraced layers of red earth reveal the method of mining. Caraj#225;s is an openpit mine, in which minerals are removed from the surface one layer at a time. In 2007, 296 million metric tons of iron ore were pulled from the
Globally, iron ore production in 2018 was expected to increase slightly from that of 2017, primarily owing to increased production in Australia and the completion of a mine in Brazil. resources are estimated to be 110 billion tons of iron ore containing about 27 billion tons of iron. resources are mainly lowgrade taconitetype ores
In 2018, iron ore mine production in Brazil amounted to approximately 450 million metric tons, a decrease of less than one percent in comparison to the previous year.
Brazil is the worlds ninthlargest country and has rich reserves of important metals such as bauxite (Aluminum), iron ore, niobium and nickel. Brazil is also a leading producer of precious metals such as gold. Mineral products and mining account for 2% of Brazils GDP. The iron ore is the most important in Brazilian exports,
Mining Many Mines. Not only does Brazil have a large supply of freshwater resources, but Brazil also has a wide variety of natural resources mined every year. These elements and metals include gold, aluminum, ironore, diamonds, emeralds and traces of many others.
SNIM Open Pit Iron Ore Mining Mauritania Mining Openpit mining of direct shipping hematite ore, using rotary drills, small shovels and trucks, commenced in 1963 at FDerik, Rouessa and Tazadit. Primary and secondary crushing is done at Tazadit and the ore is railed to Nouadhibou in trains of up to 220 cars, each carrying 84t.
Open cast mining in the Amazonian rainforest. Guyana . Brazil, maybe the worlds largest copper reserve (iron ore, manganese and gold are already found there), wood from surrounding forest is cut for charcoal to fuel pig iron plants, resulting in annual deforestation of 6,100 km 21.

#0183;#32;The mining activities on Serra Norte are concentrated on two iron orebodies (N4 and N5) and were started by 1984 with the N4E mine. Now spanning five simultaneous openpit mine operations, Caraj#225;s complex presented a strong performance in the second quarter of 2014 reaching an iron ore production of Mt.
four openpit iron mines in Caraj#225;s, and has another 90 million metric tons per year one in the opening phase. The complex is the biggest producer of iron ore in the world, making a product with high iron content (around 66%) and low concentrations of impurities. S11D will supply 90 million metric tons of

The Caraj#225;s Mine is the largest iron ore mine in the world. It is located in the municipality of Parauapebas, state of Par#225; in the Caraj#225;s Mountains of Northern Brazil . The mine is operated as an openpit mine, and is estimated to contain roughly 100 kg tons of iron ore,
The terraced appearance is a result of the open pit mining method, in which layers are excavated one at a time. Nine iron ore deposits exist along the Serra Norte (Northern Range). According to a 2013 study, mining at four of Serra Nortes main pits had produced billion tons of highgrade iron ore.
