Abstract The influence of particle size, blend ratio and some selective bio additives on the rheological behaviour of an Indian iron ore sample in a slurry concentration range of 6075% by mass was evaluated. The rheological parameters were measured using a highprecision ThermoFisher Scientific HAAKETM RheoStressTM 1 Rheometer. The iron ore slurry samples indicated non Newtonian flow

Iron Ore Pelletizing Process An Overview IntechOpen

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process

Particle Size Analysis for Mining and Minerals

In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.
