The new pelletizing method was investigated to counteract the depletion of high-grade iron ore by utilizing low-grade limonite ores based on the characterization of thermal and …
The remaining 2% of domestic iron ore was produced for non-steel end uses. Seven open-pit iron ore mines (each with associated concentration and pelletizing plants), and three iron metallic plants—one direct-reduced iron (DRI) plant and two hot-briquetted iron (HBI) plants— operated during the year to supply steelmaking raw materials.
Pelletization refers to the process of converting iron ore fines into agglomerates by mixing them with a binder and water to produce pellets, which are then dried and heated to …
Traditionally, fine ores are treated either by the process of sintering and/or by pelletizing to prepare an agglomerate with suitable metallurgical characteristics for ironmaking processes.
technologies (sintering first and after pelletizing) played an important role, making available sinter and pellets as feedstock for blast furnaces a nd direct reduction reactors. Particularly, in
For sintering and pelletizing processes, which account for the highest proportion of pollution emissions in the steel industry, the former Ministry of Environmental Protection issued Emission standard of air pollutants for sintering and pelletizing of iron and steel industry (GB 28662–2012) [10] in 2012, with special emission limits (referred ...
