fine ore sintering

What are manganese ore fines and how are they sintered?

Dec 18, 2017· Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become "agglomerated"). "The mines produce a lot of fines," Hockaday explained. "But they can't sell them, as furnaces won't buy materials that are too fine."

In this chapter, the sintering process is first described and the key steps of the sintering process, namely, granulation and thermal densification, are identified.

Ore Assimilation and Secondary Phases by Sintering of Rich ...

During the iron ore sintering process, two types of particles are present in the sinter bed: (1) fines, which are actively taking part in melting and the formation of secondary phases, and (2) coarse ores, which are partially interacting with the surrounding melt. The quality of the final sinter is particularly determined by the secondary phases and their bonding ability.

What is sinter feed? | AnswersDrive

Sinter feed is an iron concentrate containing fine particles and moisture and, being similar to iron ore fines,"1 is at risk of liquefaction, resulting in cargo shift and loss of stability. Liquefaction is believed to have resulted in a number of casualties, causing the loss of many seafarers' lives.
