11.23 Taconite Ore Processing

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat.

iron processing - Ores | Britannica

Through the process of iron ore sintering, iron is reduced through diffusion, thus removing non-iron particles prior to further application-specific processing. Coke may be used for iron ore sintering. To understand iron ore sintering, it is necessary to first understand certain aspects of raw iron ore.

What Is Iron Ore Sintering? (with pictures)

 · Iron Unleashed. The substitution of coke for charcoal unleashed cheap coal on the iron production process. It also had a direct effect on blast furnace design. The brittleness of charcoal had prevented furnaces from growing too large, lest the fuel be crushed to ash under its own weight. But coke was much more resistant to compression.
