Abstract. Pelletizing and sintering have historically been developed out of the necessity of treating different types of raw materials, of which screen analyses define the respective fields of application; thus they act as supplementary rather than competitive methods. Diminishing supply of high-grade iron ores will call for the utilization of ...

2018年7月11日 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.

Before moving on to sintering and pelletizing, I would like to give a bit description about agglomeration process. What is Agglomeration? It is the process of converting separate particles into mass or cluster. An enormous number of fines (40-50%) is generated during mining and ore dressing operations. Fines cannot be used directly in the blast ...
