A real-scale plant trail was carried out to reduce emissions of PCDD/Fs from the iron ore sintering process by optimizing its sinter raw mix (Chen et al., 2016). Compared with the reference conditions (existing raw mix), the emissions of total PCDD/Fs, I-TEQ, and WHO-TEQ was found to decrease by 65%, 76%, and 75%, respectively, as …

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.
