Currently, the regional iron ore market conditions lead to the use of high-gangue ores. The sintering of high-SiO 2 iron ores is typical for the region of Central Europe and Eastern Europe, where iron ores from Ukraine and Russia are processed. The silica content in the final sinter reaches 7–10 wt % SiO 2 [].Another region with high-gangue sintering is India, where the domestic high-alumina ...
