Among them, the iron and steel industry are concentrated in Shanxi Province, which is a major air pollution source in this region. In 2015, the emissions from the iron and steel industry in Shanxi Province accounted for 4.9%, 6.2% and 5.0% of the provincial NO x, SO 2 and PM total emissions, respectively (Wang et al., 2019).
The emissions of SO 2 and PM from sintering, pelletizing, BF, BOF, and EAF all significantly decreased. Hebei, Jiangsu, Shandong, Liaoning, Shanxi, Henan, and Hubei are hot spots for the air pollutant emissions of the iron and steel industry.

The types of coal involved in iron and steel-making systems include coking coal, sintering (pelletizing) coal and spray-blow coal. It was determined that the coal oxidation factors of coking coal, sintering coal and spray-blow coal are 0.9351, 0.9995, …
The concentration of low-grade iron ores is vital to the continued availability of iron and steel in our everyday lives (Eisele and Kawatra, 2003;Kawatra and Claremboux, 2021a;Zhang et al., 2021).
This presents a huge opportunity for suppliers of premium iron ore," said Rohan Kendall, head of iron ore research. "Although the rise in scrap consumption would lead to total …
Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process.
As the needs of the steel industry change, one production component looks to be increasingly important in meeting the needs of the modern …
Iron and steel industry is the economic pillar of a country, which is relevant to many vital industrial chains. According to a report released by World Steel Association (WSA) in 2023, the world's crude steel output has increased from 189 mt in 2000 to 1885 mt in 2022. ... In sintering and pelletizing, iron ore fines are adhesively mixed with ...
There is no denying the fact that pelletizing will remain crucial in future for steelmaking in general and it can support the transition to green, carbon-neutral steel production. For this, the pelletizing process needs to reduce its CO 2 footprint, this can be achieved using Outotec's NextGen Pelletizing vision, which recommends
