Magnetite FAQ Section
What makes magnetite different from other iron ores?
Magnetite contains the highest iron content (72.4%) among all naturally occurring iron ores. Unlike hematite, magnetite is ferrimagnetic, meaning it's strongly attracted to magnets. This unique property enables specialized applications in separation processes, data storage, and medical technology that other iron oxides cannot perform.
How should magnetite be stored for optimal preservation?
Magnetite should be stored in dry, cool conditions away from moisture and oxidizing agents. Keep containers tightly sealed to prevent moisture absorption. Bulk magnetite should be stored on pallets in a well-ventilated area. While magnetite is generally stable, prolonged exposure to humid conditions may lead to surface oxidation. For long-term storage, consider using desiccants or nitrogen blankets in storage containers.
Can magnetite particle size be customized for specific applications?
Yes, we offer magnetite in various particle size distributions from 45 microns up to 150 microns. Finer grades (45-75 microns) are preferred for dense media separation and ferrofluids, while coarser particles (100-150 microns) are better for water filtration systems. We can customize particle size distributions based on your specific process requirements and provide detailed particle size analysis reports with each shipment.
