Influence of Low-Alkali Red Mud on the Composition and Structure of Sintering Batch Consisting of Heterogeneous Iron-Ore Concentrates

摘要

The influence of low-alkali red mud on the composition and structure of pelletized sintering batch at OAO Severstal' consisting of ferruginous-quartzite ore from the Olenegorsk and Yakovlevsk deposits and magmatic ore from the Kovdor deposit is analyzed. In pelletization, the addition of low-alkali red mud improves the granulation, with increase in the mean granule diameter. The distribution of the main melt-forming elements among the batch fractions is established.
