Pyroxenite powder can be used as a flux in iron making, as a source of MgO in hematite pellet sintering, and in the manufacture of aggregates for concrete admixtures. It also plays a role in the formation of magnesioferrite and high-melting slag, impacting the quality and microstructure of the final product.
Detailed Uses:
- Metallurgy and Iron Making:Pyroxenite, particularly in powdered form, is valuable in iron making as a flux. It helps to modify the slag composition, leading to improved metallurgical properties.
- Hematite Pellet Sintering:Pyroxenite can be used as a source of MgO in hematite pellet sintering. This process improves the sintering characteristics and ultimately the quality of the final pellets.
- Concrete Aggregates:Pyroxenite can be processed into aggregates, which are then used as admixtures in concrete construction. Its unique mechanical and thermal properties, along with the high concentration of magnesium oxide, make it a suitable component for this purpose.
- Other Applications:Pyroxenite is also explored for its potential in other areas, such as:
Fluxing agent in blast furnaces: Replacing dolomite, it reduces energy requirements and improves burden permeability.
CO2 sequestration: Fine-ground pyroxenite can react with atmospheric CO2, helping mitigate climate change.
Foundry sand: Pyroxenite can be used in steel foundries as a foundry sand.
Geothermal applications: Pyroxenite can be used in steam baths for potential healing properties.
