types of iron ore: hematite vs. magnetite | inn

For investors interested in the iron ore space, it’s useful to know the facts about hematite and magnetite ores. Both of those types of iron ore are rocks and minerals from which iron can be extracted. Here’s an overview of some basic information about hematite and magnetite ores, including what they are and where they’re found

Hematite ore is a direct-shipping ore with naturally high iron content. Because of its high iron content, hematite ore must undergo only a simple crushing, screening and blending process before being shipped off for steel production

For that reason, hematite ore is important for many mining companies. As Australia’s Magnetite Network explains, “[d]irect shipping ores, when mined, typically have iron (Fe) content of between 56% Fe and 64% Fe … By comparison, magnetite ore typically has a much lower iron content when mined of between 25% and 40% Fe and in this form is unsuitable for steel making.”

Hematite ore is found throughout the world, but the most utilized deposits are in Brazil, Australia and Asia. Hematite ore has been the primary type of iron ore mined in Australia since the early 1960s

Approximately 96 percent of the continent’s iron ore exports are high-grade hematite ore, and the majority of its reserves are located in the Hamersley province of Western Australia. 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 this type of iron ore. Its Carajas mine is the largest iron ore mine in existence, and is operated by Brazilian miner Vale (NYSE:VALE). Vale is the third-largest mining company in the world and the largest producer of iron ore pellets. Vale’s headquarters are in Rio de Janeiro, and its primary iron ore assets are in the Iron Quadrangle region of Minas Gerais

The mineral magnetite actually has higher iron content than the mineral hematite. However, while hematite ore generally contains large concentrations of hematite, magnetite ore generally holds low concentrations of magnetite. As a result, this type of iron ore ore must be concentrated before it can be used to produce steel. Magnetite ore’s magnetic properties are helpful during this process

While magnetite ore requires more treatment, end products made from magnetite ore are typically of higher quality than those made from hematite ore. That’s because magnetite ore has fewer impurities than hematite ore; in this way, the elevated cost of processing magnetite ore can be balanced out

Magnetite ore is currently mined in Minnesota and Michigan in the US, as well as in taconite deposits in Eastern Canada. A major mining site in Michigan is the Marquette Range. The deposit was discovered in 1844, and ore was first mined there in 1848. Magnetite ore and hematite ore are among the four types of iron ore deposits found in this area

In Minnesota, this type of iron ore is mined mainly in the Mesabi Range, one of the four ranges that make up the Iron Range of Minnesota. In Canada, Labrador is home to the majority of magnetite ore mining. In particular, mining companies focus on exploration and development in the iron-rich Labrador Trough

Cleveland-Cliffs (NYSE:CLF) is a major player in the magnetite ore industry, with five iron ore mines that are focused on magnetite ore. For instance, the Empire mine, located in Michigan’s Marquette Range, has an annual capacity of 4.5 million tons. Additionally, its Hibbing taconite mine is in Minnesota’s Mesabi Range and has an annual capacity of 8 million tons of magnetite ore

In Canada, there are financial incentives to extract magnetite from mine tailings for export. Whitehorse Yukon has a rich magnetite deposit of this type with interest to see partner or buyer getting to the steel mills

The two ores of iron are hematite and magnetite with the chemical formula Fe2O3 and Fe3O4 respectively. To determine which of the compounds has a higher percentage of iron per kilogram first the molar mass of the two compounds has to be determined. Iron has a molar mass of 55.845 g/mole and oxygen has a molar mass of 16 g/mole. The molar mass of Fe2O3 is 159.69 and that of Fe3O4 is 231.535. In hematite the percentage of iron by mass is `111.69/159.69 ~~ 69.9%` , similarly in magnetite the percentage of iron by mass is approximately 72.3% Magnetite has a higher percentage of iron per kilogram as compared to hematite

Iron ore pellets are made from both magnetite and hematite ores. Hematite ores are concentrated using a flotation process. Pellets include a mineral binder that represents about 2% by weight. Much of the ore in pellets made from magnetite is oxidized to hematite during the high-temperature induration process that sets the binder. Induration is necessary to instill the durability necessary to support a blast furnace burden, and to mitigate fines generation during shipping & handling. Direct shipping lumpy ore is now very scarce. Fine iron ore must be agglomerated before being fed to a blast furnace either by pelletizing or sintering, which is normally done at the steel mill. Fine iron ore cannot be fed to a blast furnace, or it will plug. The burden b=must be sufficiently porous to allow the wind to penetrate the birden. Sintering also provides a means to recycle steel mill wastes, including pellet chips, pit scrap and BOF dust

Atomic weights of Fe at 56 and oxygen at 16. In chemically pure minerals the percentage Fe in hematite Fe2O3 is 112/(112+48)=70%. Percentage Fe in magnetite Fe3O4 is 168/(168+64)=72.4%. In nature magnetite often contains impurities in the ore which makes the Fe content of mined ore lower than hematite. As stated the impurities in magnetite can be removed via processing often resulting in an Fe percentage higher than hematite

“Hematite ore has the chemical formula Fe2O3 and has a very high iron content of 70 percent. … With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore.” No matter how I count it, Fe2/Fe2O3 comes as lower a mass fraction than Fe3/Fe3O4. So the statements above make little sense to me

So the statements above make little sense to me

If I remember my chemistry, %Fe in (pure) magnetite is 70% and is actually higher than the %Fe in (pure) haematite which is 67.5%. So the opening line in the section on magnetite above is perhaps misleading since it is not the chemical composition which is the difference. The difference is the level of impurities in magnetite deposits which are removed by magnetic seperation and then pelletising is needed to agglomerate the fine magnetite material. This gives a pellet which is more expensive than high grade haematites but with a higher %Fe as the author then correctly states
