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 ...

Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become "agglomerated"). "The mines produce a lot of fines," Hockaday explained. "But they can't sell them, as furnaces won't buy materials that are too fine.".

Sintering of Iron Ore Fines Sintering is an agglomeration-technique for enlarging the iron ore particle size. The use of iron ore sinter in a modern day blast furnace has become common due to various advantages associated with it. The merits of sintering process are listed below in comparison to iron ore pellets: (i) The sintering process uses ...

Specifically, iron ore sintering requires the use of fine ore, produced by crushing high-grade iron ore into particles only a few millimeters in diameter. Depending on the specific machine and iron ore sintering process used, substances such as coke breeze and burnt limestone are used to ignite and heat the iron ore particles until the ...

The whole melting curve of iron ore during sintering process was obtained, and the melting characteristics of iron ore were defined and explained. The whole melting process of mixture, mixed by iron ore and CaO reagent at basicity of 2. 0 and 4. 0, respectively, was observed using a SiC heating furnace with camcorder unit, and the melting curves of mixture that were relative height vs ...
