Aguas Claras Iron Ore

The exploration, monitoring and analysis of iron ore resources based on remote sensing have broad application value. Huang et al. [10] used multi-source satellite sensors such as Landsat, Aster ...

Owners of this iron-ore mine in Brazil saw mining as a temporary use of the land and began planning in the early 1990s to reuse the excavated pit once mineral resources are depleted. ... Aguas Claras is an ideal location for a village since the mine is on the rear slope of mountains that form the southern boundary of the burgeoning city of Belo ...

This page is a summary of: Comparison of Altered Mineral Information Extracted from ETM+, ASTER and Hyperion data in Águas Claras Iron Ore, Brazil, IET Image Processing, September 2018, the Institution of Engineering and Technology (the IET), DOI: 10.1049/iet-ipr.2018.5026.

The Aguas Claras and Mutuca iron ore mines, reached the watertable in the 80's, starting the dewatering by using series of deep wells. In the 90's, some communities located near the mines, complained about the possible interference in the stream's outflows and so, the areas covered by hydrogeological studies were enlarged in order to embrace the neighbourhood of the mines.

Unlike other mines in the QF, the Águas Claras Mine contained mainly high-grade ores hosted within dolomitic itabirite. Two distinct types of high-grade ore occurred at the mine: soft and hard. The soft ore was the most abundant and represented more than 85% of the total ore mined until it was mined out in 2002.

Rock samples cannot fully represent extraction results on an image. Here, alteration information associated with the Aguas Claras, Brazil iron deposit was analysed using a Landsat Enhanced Thematic Mapper plus (ETM+), a Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Hyperion data, all with 30 m resolution.

A ́ guas Claras iron mine is located on the northern edge of the Serra do Curral, in a northeast-southwest trending homocline with bedding dipping steeply to the southeast ( Fig. 2A).

Iron ore is regarded as the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trillion-dollar-a-year metal ...

Location. The Águas Claras and Pau Branco iron ore deposits are located in the QF, in south-eastern Brazil, within the state of Minas Gerais (Fig. 1).The QF is one of the most important mineral provinces in the world, hosting world-class orogenic gold and iron ore deposits (Lobato et al. 2001; Rosière et al. 2008).Open-pit mining at Águas Claras commenced in 1973 …

The Mina de Águas Claras is an open pit mine in the Brazilian federal state of Minas Gerais in which iron ore was extracted from 1971 to 2002. DYWIDAG provided the material used in the stabilization of the slope where the mine is located. ... approximately 300 million tons of iron ore were extracted from Águas Claras over an area of roughly 1 ...

Beukes et al. (2002) suggest that the soft high-grade iron ore of theÁguas Claras Mine is a supergene-modified hydrothermal ore, considering that the dolomitic itabirite (proto-ore) "obviously ...

Dolomitic itabirite is the protore of the soft high-grade iron ore, which is the main ore type of the Águas Claras orebody, representing about 85% of the 284 Mt mined since 1973, with the ...

Details of the common iron ore and associated gangue minerals found in many iron ore deposits and iron ore products are given in Table 2.1.The three most common iron ore minerals are magnetite, hematite (the spelling "hematite" is preferred here over "haematite"), and goethite, which together account for an estimated > 99% of the iron minerals contained in …

The soft high-grade ores, together with the low-grade ores, called iron-rich itabirite, are the main types of ore, and represent approximately 51 and 29% of the reserves respectively. The remaining 20% comprises of high-grade hard ore. The iron oxide mineralogy is the same as that of the Aguas Claras Mine, but in different proportions.
