The main difference between these two minerals lies in their chemical composition, which affects their geologic formation and physical characteristics.
Hematite is formed by weathering processes in sedimentary rocks or through hydrothermal alteration of pre-existing rocks. It is often found in banded iron formations, which are layered sedimentary rocks that were deposited over billions of years ago. On the other hand, magnetite forms during igneous processes such as volcanic eruptions or as a result of metamorphism in pre-existing rocks. Its occurrence can be found in mafic and ultramafic igneous rocks and some metamorphic rocks. With this understanding on how they’re formed, let’s now move on to a discussion about their physical characteristics.
Physical Characteristics
You can easily differentiate hematite from magnetite by their physical characteristics, like how a flamingo stands out in a flock of seagulls. Hematite has a reddish-brown color and is more opaque than magnetite. It also has a distinctive red streak when rubbed against porcelain.
In terms of crystal structure, hematite has hexagonal symmetry while magnetite has cubic symmetry. The geological occurrence of both ore types is also different. Hematite is commonly found in sedimentary rocks such as banded iron formations, whereas magnetite is often found in igneous and metamorphic rocks. Understanding these physical characteristics and geological occurrences can help you identify the type of ore you are dealing with for various applications, which we will explore in the subsequent section about hematite applications.
Hematite Applications
If you’re interested in hematite, it’s important to know its various applications. Hematite is commonly used in steel production due to its high iron content and ability to purify metal. It’s also a popular material for jewelry making thanks to its metallic luster and durability. In addition, hematite is widely utilized as pigments and dyes in industries such as cosmetics, paints, and ceramics.
Steel Production
Steel production heavily relies on hematite and magnetite as sources of iron ore, with the former being preferred due to its higher iron content. Raw materials like these play a crucial role in meeting global demand for steel products, which are used in various industries such as construction, manufacturing, and transportation. Here are some ways that hematite contributes to steel production:
- Hematite is mined from deposits around the world and can be easily extracted due to its abundance.
- Once extracted, hematite undergoes a process called beneficiation where impurities are removed and the iron content is increased. This results in high-grade iron ore that can be used in blast furnaces to produce steel.
Meanwhile, magnetite also plays a role in steel production but is less commonly used compared to hematite due to its lower availability and higher processing costs. Nevertheless, it still has some advantages over hematite such as:
- Magnetite has a higher concentration of iron than hematite which means that less raw material is needed to produce the same amount of steel.
- Its magnetic properties make it easier to separate from other minerals during beneficiation.
As you delve deeper into the world of ore types, you’ll discover how they’re not only essential for practical applications like steel production but also for aesthetic purposes such as jewelry making.

Whether you choose natural or synthetic pigments for your jewelry designs is up to you – just remember that each has its own unique historical significance.
Now let’s transition into the subsequent section about magnetite applications by exploring another aspect of mineralogy: ore types!
Magnetite Applications
One notable application of magnetite is in the production of dense medium separation, commonly used in coal washing processes. This process involves using a mixture of finely ground magnetite and water to separate coal from rock and other impurities. Magnetite’s high density allows it to sink to the bottom of a tank, while the lighter coal floats on top, making it easier to separate and recover.
Aside from its use in coal washing, magnetite has many other applications. In medicine, for example, magnetic nanoparticles made from magnetite can be used as contrast agents for magnetic resonance imaging (MRI). Magnetite also has potential uses in environmental remediation, such as removing heavy metals from polluted water or soil. Despite these benefits, however, there are both pros and cons to using hematite versus magnetite in various applications.
Pros and Cons of Hematite and Magnetite
Deciding between hematite and magnetite for various applications comes with its own set of advantages and disadvantages. Hematite, which is primarily found in banded iron formations, has a lower iron content than magnetite. However, it is easier to process due to its softness and can be extracted through open-pit mining or underground mining methods. Additionally, hematite does not require as much energy during processing as magnetite does.
On the other hand, magnetite has a higher iron content than hematite and is commonly found in igneous rocks. While it requires more energy to process, magnetite can be extracted using more efficient techniques such as dry magnetic separation or wet magnetic separation. This makes it an ideal choice for steelmaking industries that require high-grade iron ore. Furthermore, unlike hematite, magnetite deposits are less prone to impurities such as phosphorous and sulfur.
Considering both the pros and cons of hematite and magnetite extraction methods and geological occurrence can help you make an informed decision on which ore type would work best for your specific application.
