Tehran, Iran [email protected]. INTRODUCTION. Substantial Increase of . Iron ore price over the last few . years, bring attention to Hematite exploration more than before. The conventional geophysical technique for iron ore exploration is magnetic method which is not a reliable means of targeting hematite mineralisation

The largest iron deposits in the world are spread out across countries. Australia's crude ore reserves, for instance, were two times larger than that of Russia.

This paper presents an overview about the XIV iron-oxide prospect which is located in the Bafq mining district, central Iran. The prospect and its host rocks were investigated by field observations together with mineralogical and geochemical studies. According to these investigations, the XIV prospect is similar to Kiruna-type iron deposits and demonstrates a magmatic source for the ore ...

The Choghart magnetite-apatite deposit situated in the Bafq district, Central Iran, has been scrutinized for rare earth elements (REEs) by precise geochemical investigation. The Central Iran is a susceptible area of rare earth elements. One of the Choghart's prominent points is the existence of hydrothermal zones which made prediction of REEs occurrence within the deposit possible.

The Sarviyan iron deposit is located 30 km northeast of Delijan city in Markazi Province, Iran. The iron ores occur dominantly as irregular masses and veins in a Middle-Late Eocene volcano-sedimentary sequence, adjacent to Eocene-Oligocene plutonic rocks. Magnetite is the main ore mineral accompanied by hematite, goethite, pyrite, and chalcopyrite.

Gol Gohar Mining Area With iron ore rich mines as one of the most prominent active mining poles in the Middle East, it has the potential to become a large and competitive area in Iran and even worldwide. These deposits are located in Kerman province, 50 km southwest of Sirjan.

Although not all salt diapirs contain iron ores, considerable quantities of the ore deposits are known in Iranian salt diapirs (e.g., Hormuz, Pohl, Larak, Hengam, Bustaneh, Gachin, Champeh, Chah-Musallem, Charak, and Kurdeh) necessitate the diapirs to be investigated with special views on the origin and mechanism of the iron ores' formation.

Keywords: iron oxide-apatite, petrography, geochemistry, Sechahun, Bafq 1. Introduction The Posht-e-Badam Block in Central-East Iranian microcontinent is known as the main metallogenic province of Iran, hosting many ore deposits particularly iron oxide-apatite (IOA), Fe-Mn exhalative, and Zn-Pb

Iron ore western centeral eastern Exploration Detail: 26km 8km This mine is one of the largest mineral areas in Iran, also considered to be one of the Middle East's richest deposits. it is divided in three major zones; western, central and eastern. These iron ore deposits contain a total geological resource of 1.2 billion tons of mostly magnetite with a Fe grade from 27 to 61%.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Other deposits of volcanic iron ore are the Chilean Iron Belt, the Tertiary Cerro el Mercado deposit in Mexico, the Eocambrian Bafq district in Iran, and the Proterozoic Kiruna field in Sweden. Of these, Sierra Bandera in the Chilean iron belt may be another example of surface volcanic iron ore rather than subvolcanic ore as is commonly assumed ...

The Sangan iron ore deposits form part of the east-west trending Kuh-e-Taleb mountain range, and in the Khorasan-Razavi Province in north-eastern …

The Sangan world-class iron deposit is located in northeastern Iran, about 40 km from Khaf city, Razavi Khorasan Province. The intrusion of Middle Eocene granitoid plutons of I-type into Cretaceous carbonate rocks has formed a hydrothermal skarn system with iron mineralization in seven ore bodies in the Sangan ore deposit.

"The types of deposits that lend themselves to remote sensing in Iran are intrusive deposits," says Rowan. He explains that intrusive ore deposits form deep underground. Magma from the Earth's mantle percolates into the Earth's crust in areas where two tectonic plates …

Iran's copper deposits have a relative advantage over the rest of the world in that the average grade of known porphyry copper deposits, with reserves exceeding 2.5 billion tons, is above 0.7 percent. Gold, molybdenum, and occasionally silver, are associated with copper in all known porphyry copper deposits.

Geological and economic modeling of an ore body and also optimization of the depth at which transition is made from open-pit to underground mining is an important part of the mining design process in large and massive deposits. In this paper, a geological block model of Chah-Gaz iron ore deposit located in Iran was first created based on iron ore cut-off grade. Then with considering the ...

Where Iron Ore is Mined. Iron ore is mined and produced in countries around the world including China, Australia, Brazil, India, Russia, Ukraine, South Africa, United States, Iran, Canada, Sweden and Kazakhstan. The Brazilian mining corporation Vale is the largest iron ore producer in the world.

In the Zanjan district of northwestern Iran, there are some iron oxide–apatite deposits associated with plutonic rocks (Nabatian 2012; Nabatian et al. 2013).Many such mineral systems, including Sorkhe-Dizaj, Morvarid, Aliabad, and Zaker deposits, have been discovered there (Figs. 1 and 2).Each deposit consists of multiple veins, each vein usually having less than 1,000 tons of ore, but …

Iron (Fe) is a metallic element which constitutes about 5% of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Almost all iron ore is used in blast furnaces to make pig iron ...

The Chadormalu magnetite-apatite deposit in Bafq metallogenic province, Central Iran, is hosted in the late Precambrian-lower Cambrian volcano-sedimentary rocks with sodic, calcic, and potassic alterations characteristic of iron oxide copper-gold (IOCG) and iron oxide-apatite (IOA) ore systems. Apatite occurs as scattered irregular veinlets and disseminated grains, respectively, within and in ...

The Pivehzhan iron deposit is located at about 80km southwest of Mashhad, NE Iran. It occur within the Devonian carbonates as lenticular and massive bodies, as well as veinlets of magnetite and iron sulphides, transformed to goethite and haematite by weathering …

Host rocks of the iron oxide- apatite deposits (IOA) in the Bafgh mining district are composed of plutonic and volcanic rocks that originated from enriched mantle. The high amount of LREE/HREE ratio in these deposits indicates a progressive magmatic

Iron (Fe) and manganese (Mn) are among the major elements in the Earth's crust with abundances of 5.76 and 0.1 wt%, respectively ().Iron, Mn and Fe-Mn deposits have different origins and have formed throughout the period of formation of the Earth's crust in various geological settings (Dill, 2010, Maynard, 2010, Dill et al., 2013, Kuleshov, 2017).

The Sorkhe‐Dizaj iron oxide–apatite deposit in the Cenozoic Alborz‐Azarbaijan magmatic belt, NW Iran, is hosted mainly by a Late Eocene to Oligocene quartz‐monzonitic body, and subordinately in the Eocene volcanic and volcanoclastic sequences. The Sorkhe‐Dizaj intrusive body is an I‐type granitoid of the calc‐alkaline series.

More than 90 percent of Iran's iron ore deposits are located in three provinces listed in Table 11, while Table 12 presents a comparison of Iran's iron ores with the rest of the world. The share of Iran in worldwide iron reserves stands at 2.7 to 3 percent, while its share in world production varies form 0.9 to 1.0 percent.
