Fines, however, must first be agglomerated, which means reforming them into lumps of suitable size by a process calledsintering. Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together.

Iron processing Britannica

Despite the military demand for cast iron, most civil applications required malleable iron, which until then had been made directly in a bloomery. The arrival of blast furnaces, however, opened up an alternative manufacturing route; this involved converting cast iron towrought ironby a process known as fining. Pieces of cast iron were placed on a finery hearth, on which charcoal was being burned with a plentiful …

Iron Ore Reduction an overview ScienceDirect Topics

Theiron-ore finesthat enter the BF need to go through a pelletizing and sinteringprocess. In other cases, such as the smelting reduction (SR) processes that use the fluidized bed technologies theiron-ore finescan directly be charged into the reductionprocessmaking it highly advantageous.

Introduction to Iron ore Pellets and Pelletizing processes

Pelletizingis a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

A Look at theProcessof PelletizingIron Orefor Steel

In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning. The mixing step sets the stage for the remainder of the process, creating a homogeneous mixture that will allow for a uniform product to be created. In order to pelletize iron ore fines and/or concentrate, a binder is needed.
