Ore Sintering - an overview ScienceDirect Topics
2010-4-2 As described in Chapter 14 on iron ore sintering, sintering involves the combustion of fossil fuels like coal and coke breeze to generate the heat required for sintering reactions. Therefore, emissions from the sintering process arise primarily from the combustion reactions in the sintering bed on the traveling sinter strand.

Sintering: A Step Between Mining Iron Ore and
2019-6-11 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.

During the iron ore sintering process, two types of particles are present in the sinter bed: (1) fines, which are actively taking part in melting and the formation of secondary phases, and (2) coarse ores, which are partially interacting with the surrounding melt. The quality of the final sinter is particularly determined by the secondary phases and their bonding ability.
