Magnetite
Importantly, magnetite is suitable for processing into iron ore pellets for use in modern steel production and currently accounts for approximately 50% of global iron ore production. The magnetic properties of magnetite enable it to be readily refined into an iron ore concentrate used as high-quality feedstock for the production of premium quality,
Sierra Metals to Invest US$28 Million for an Iron Ore Processing Plant

Mining – Karara Mining
Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.
Circored Fine Ore Direct Reduction Plus DRI Smelting: Proven
Key features of the Circored process. Preheating the iron ore fines to 850–900 °C in a separate CFB reactor for calcining prior to charging in the primary CFB reduction stage. This method also allows the processing of magnetite ores, which can be difficult to reduce as the preheating stage oxidizes the magnetite to hematite.

Iron Ore Statistics and Information | U.S. Geological Survey
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
