Depletion trend of high-grade iron ore resources have become significant due to the recent increase in world steel production. Therefore, effective utilization low-grade and low-quality ores has been will be strongly required. Since concentrates obtained by beneficiation processes are usually fine, e.g., less than 100 µm particles size, it is difficult directly use a large amount them sintering...

The iron content of the ore used is crucial for the productivity and coke consumption rate in blast furnace pig iron production. Therefore, most iron ore deposits are processed in beneficiation plants to increase the iron content and remove impurities. In several comminution stages, the particle size of the ore is reduced to ensure that the iron oxides are physically liberated from the gangue. ...

J. Korol, Central Mining Institute, Department of Material Engineering, Poland D. Burchart-Korol, A. Smoliński, Central Mining Institute, Department of Energy Saving and Air Protection, Poland In this study composition of sinter mixtures used in Polish sinter plants were established. Seven sinter mixtures composition were examined, based on iron-bearing materials, admixtures and fuels.

Crack detection for iron ore green pellet is an essential step in the measuring process of drop strength, which one important quality metrics pellet. However, current method crack manual inspection, rather laborious, tedious and subjective. Although various deep network-based methods are proposed to automatically detect cracks tunnel, pavement wall, little effort has been made on detection. The...

For decades, the extraction of minerals has intensified in order to meet the demand of industry. Iron ore deposits are important sources of metals, such as iron (Fe) and manganese (Mn). The particulate ores can be dispersed during extraction, transport and storage, with potential to induce biological impacts. Amphibians are very sensitive to environmental stressors. Therefore, the present study...
