Types of Iron Ore: Hematite vs. Magnetite | INN
Fine iron ore must be agglomerated before being fed to a blast furnace either by pelletizing or sintering, which is normally done at the steel mill. Fine iron ore cannot be fed to a blast furnace ...
Magnetite – A Higher-grade Blast Furnace Feed and Its ...
The corresponding premium for blast furnace (BF)-grade magnetite concentrate is 17 per cent, which demonstrates the dependency on grade. The capital expenses for a 14 Mt/a concentrate plant is estimated at US$3.1 B for BF-grade magnetite and US$3.35 B for DR-grade, with operating expenses at US$45 and US$50 respectively.
The Extraction of Iron - Chemistry LibreTexts
Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.

Creating steel from low-grade iron ore requires a long process of mining, crushing,
Iron ore - Wikipedia
Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces.

Direct reduced iron - Wikipedia
Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example being heating iron ore in a furnace at a high temperature of 800 to 1,200 °C...
Magnetite Concentrate Market Study | CRU
Nov 05, 2019 · The client was expanding an existing iron ore mine in Australia to produce 7-8mt tpy of magnetite pellet feed. The client was concerned about the future market for magnetite pellets in blast furnaces in the period to 2038 and requested that we investigate this and alternative markets.
