LKAB Minerals supplies MagnaDense from owned Magnetite resources, ensuring long-term availability and consistent quality.
MagnaDense product uses
Depending on your specific application, you will find that MagnaDense can bring you different advantages such as:
- Increased weight and/or density
- Reduced volumes
- Reduced heat of hydration
- High submerged / saturated density
- High radiation shielding characteristics
- Space saving
- Noise and vibration dampening
- Thermal energy storage
MagnaDense as an aggregate for heavy concrete
When you need heavy concrete with densities of up to 4.0 t/m3, you can certainly use MagnaDense. The high density concrete can be produced and placed using standard equipment.
Well-known applications for heavy concrete are:
MagnaDense loose ballast applications
With its high density MagnaDense is often used as loose ballast. Typical applications are:
Special applications for MagnaDense
Besides the above mentioned applications that use MagnaDense as a loose ballast or to produce heavy concrete, there is another niche application for MagnaDense:
LKAB Minerals wants to support innovation, therefore our R&D department is always working on identifying new products and application that can benefit from the unique properties of MagnaDense.
All specifications for our iron oxide products vary due to customising for different applications.
||62.0 - 71.7
||86 - 99
|Specific gravity (t/m3)
||4.6 - 5.1
|Bulk density (t/m3)
||2 - 4
The high density of MagnaDense results in a decreased volume for a given weight, or alternatively an increased weight per given volume, offering a better overall economy for specific projects.
- Particle density range: 4.7 – 5.2 t/m3
- Concrete density range: 2.4 – 4.0 t/m3
- Complies with EN 12620; MagnaDense complies with European requirements for aggregates to be used in concrete.
MagnaDense standard grades
MagnaDense is available in coarse and fine grades as well as mixtures of these grades and complies with requirements of EN 12620. Top sizes for our dense product ranges from 0.5mm to 20mm. Each grade has a controlled particle size distribution and has been designed to ensure the heavy dense aggregate fits your application.

We are part of the international LKAB Group. LKAB Minerals has 13 different sites across the world where local knowledge is available. Most locations have their own storage facilities and can therefore supply you on-time and economically, all year-round the best quality MagnaDense.
MagnaDense mineral origin
LKAB Minerals’ MagnaDense is manufactured from the natural mineral Magnetite which is mined in our own group resources. The LKAB mines are located in Kiruna and Malmberget in the northern part of Sweden.
The product is harmless to the environment, non-toxic in all its forms and a sustainable materials. It can be recyclable after use as was demonstrated with the recovered MagnaDense from the Draugen Offshore Platform.
