Abstract
The authors describe the effect of low-alkaline red mud on the composition and structural characteristics of pelletized charge of JSC “Severstal”, consisting of ferruginous quartzites of Olenegorskoe and Yakovlevskoe deposits and Kovdor magnezite ores. It is proved that in the process of pelletizing low-alkaline red mud additives contribute to improve the granulation process, increasing the average diameter of the granules. The distribution of the main melt forming elements was shown for fractions of pelletized charge.
