In the process of sintering, iron ore fines convert into lumpy porous mass by incipient fusion. The term incipient fusion is used because the process takes place by partial combustion of ore with a fuel within the mass itself. The produced sinter possesses strength, permeability and fluxing agents that are beneficial to steel-making operations.
