Question: Iron in the Earth is normally found in three different ores: Fe2O3 (hematite), Fe3O4 (magnetite), and FeCO3 (siderite). Calculate the percent by mass of iron in each of these ores. Which ore has the highest iron content?
When considering the entire composition of the earth, iron (Fe) is the most abundant element, but it only comprises approximately 6 percent of continental crust. Metallic iron is silvery-white, malleable, ductile, and may be readily magnetized. Elemental iron has a relatively high specific gravity (7.87) and high melting point.
The minerals with the highest iron content will be magnetite, hematite, goethite, and limonite. These minerals range in about 60% to 70%+ in iron content. Magnetite is the most widespread mineral on earth with roughly the highest iron content. This table shows the approximate percentage of iron in the mineral.

The mountainous Hamersley Range is at the center of hematite ore exploration and development because it sits on a banded iron formation. Brazil is another one of the world's main sources of hematite ore. Its Carajas mine is the largest iron ore mine in existence, and is operated by Brazilian mining company Vale (NYSE: VALE ).

Interactions between water and ferrous rocks are known to generate natural H2 in oceanic and continental domains via the oxidation of iron. Such generation has been mainly investigated through the alteration of Fe2+-silicate and some Fe2+-carbonates. So far, magnetite (α-Fe3O4) has never been considered as a potential source mineral for …
Magnetite is the best iron ore. It has the highest iron content (up to 72.4%) and the strongest magnetic power. It can be separate from gangue, producing a high-grade concentrate (above 70%) with very few impurities. Magnetite formula: Fe 3 O 4 Iron content: Up to 72.4% Magnetite color: Black Magnetite hardness: 5.5-6.5 Magnetite …
The most common iron carbonate is siderite (FeCO3 ), a frequent constituent of carbonate sediments and rocks on Earth. Siderite has a low-temperature transition at 30–35 K ( Housen et al., 1996), distinctively different from that of pyrrhotite (Section 5.08.3.9). Siderite is paramagnetic at ordinary temperatures and carries no NRM.
Magnetite may also form in high-temperature hydrothermal veins in association with ore minerals such as pyrrhotite, sphalerite and galena. ASHLAND COUNTY: Abundant constituent of the iron formation in the Gogebic Range from Mineral Lake to Hurley where it is found as small crystals and masses intergrown with siderite, chamosite, stilpomelane ...
The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the …
By far, the two most economically important iron ores are hematite and magnetite. Although hematite is more abundant than magnetite, magnetite has the higher iron content, so magnetite iron ore deposits are highly sought after.
The most important 4 types of iron ores are magnetic ore, hematite, limonite, and siderite. 1. Magnetite - the best iron ore Magnetite, also called lodestone. It is a natural magnet, hence the name, giving it a distinguishing characteristic. Magnetite is the best iron ore. It has the highest iron content (up to 72.4%) and the strongest …
Compared to pure siderite (15.2%), enhanced removal of As (III) in the range of 19.3% to 88.2% was observed, depending on the amount of incorporated citrate. The maximum sorption capacities of...

Prior studies suggested that iron phases in Lake Towuti sediments undergo dissolution during reductive diagenesis, with secondary growth of diagenetic phases such as magnetite and siderite ( Tamuntuan et al., 2015 ). However, siderite was not explicitly documented in that study, nor is it clear where in the lake and sediment these minerals …

The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe 2 O 3 ), which is red; magnetite (Fe 3 O 4 ), which is black; limonite or bog-iron ore (2Fe 2 O 3 ·3H 2 O), which is brown; and siderite (FeCO 3 ), which is pale brown. Hematite and magnetite are by far the most common types of ore.
Magnetite, hematite, goethite, limonite, and siderite are the most common forms of iron found. " Natural ore " or " direct shipping or e" refers to ore that contains a high percentage of hematite or magnetite (greater than about 60% iron) and can be fed directly into blast furnaces to produce iron.
The magnetite is associated with iron silicates, garnet, chlorite and tourmaline. (Dutton, 1971). — Small magnetite crystals in a grunerite-quartz iron formation within the Michigamme slate is found at SW 1/4 NE 1/4 Sec. 28 T.39N. R.18E. (Dutton, 1971).

There is 40-60% pure iron in limonite. Siderite contains many impurities and has pure iron of just 40-50%. Ores containing very high haematite or magnetite amounts (greater than about 60 per cent iron) are referred to as "normal ore" or "direct shipping ore," which means that they can be fed directly into blast furnaces that produce iron.
