    Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation. As shown in Figure 14.1, iron ore sintering is carried out in three stages: raw material

  • What Is Iron Ore Sintering? (with pictures)

    Oct 27, 2019· Dust from the iron ore, as well as iron particles that do not meet size requirements, are recirculated through the machine with each batch of iron ore processed. Primarily, the goals of iron ore sintering are to produce consistent chemical composition, to increase the strength of iron particles, and to create a uniform particle size.

  • Sintering: A Step Between Mining Iron Ore and Steelmaking

    World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
