Magnetite Iron Ore

Magnetite Iron Ore from Pakistan

Magnetite is a naturally magnetic iron oxide mineral (Fe₃O₄) with a characteristic dark grey to black metallic lustre. It is the most iron-rich of all common minerals, containing up to 72% Fe in its pure form. Magnetite’s strong magnetic properties allow it to be efficiently upgraded through magnetic separation, producing high-grade concentrates suitable for pellet feed, blast furnace charge, and specialty industrial applications. Pakistan’s geological formations host magnetite deposits that are actively mined and beneficiated for both domestic use and export.

Available Forms

• Run-of-mine (ROM) lumps: 10-200 mm

• Crushed ore: 0-50 mm, 0-25 mm

• Fines: 0-10 mm

• Magnetic concentrates: 62-68% Fe (wet or dry magnetic separation)

• Pellet-grade concentrates: 65-68% Fe, ground to -325 mesh

• Custom sizing and grades available

Industrial Uses

• Blast furnace ironmaking: Magnetite lumps and sinter made from magnetite fines are charged into blast furnaces as part of the iron burden. Magnetite releases heat during reduction (exothermic reaction) which improves furnace energy efficiency

• Pelletizing: Magnetite concentrates ground to fine size (-325 mesh) are the preferred feedstock for iron ore pellet plants due to their exothermic behavior during induration, reducing fuel consumption in pellet kilns

• Direct Reduced Iron (DRI): High-grade magnetite pellets (65%+ Fe) are used as feed in gas-based and coal-based DRI plants for sponge iron production

• Heavy media separation (HMS/DMS): Finely ground magnetite (ferrosilicon replacement) is used as a dense medium in coal washing, diamond recovery, and mineral beneficiation plants. The magnetic property allows easy recovery and recycling of the medium

• Coal washing: Magnetite powder is the standard dense medium in coal preparation plants for separating clean coal from refuse and middlings

• Water treatment: Magnetite nanoparticles and powder are used in advanced water treatment processes for heavy metal removal, phosphate adsorption, and magnetic flocculation

• Concrete and radiation shielding: High-density magnetite aggregates are used in heavyweight concrete for radiation shielding in nuclear facilities, hospitals, and research laboratories

• Pigments and coatings: Magnetite is used as a black iron oxide pigment in paints, primers, anti-corrosion coatings, and toner for printers and copiers

• Catalyst support: Magnetite serves as a catalyst or catalyst carrier in industrial chemical processes including ammonia synthesis (Haber process) and Fischer-Tropsch synthesis
