Fluxes: Lime stone, dolomite, dunite, pyroxinite are the main source of fluxes used in Indian iron and steel industry. However, calcined lime has an additional advantage in the sinter process like improvement in mean size, tumbler index and reducibility index. The higher size flux generates free calcined lime faces in the sinter.
Sinter plant - Wikipedia
Sinter plants agglomerate iron ore fines with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the stone properties of the …

What is the difference between sintering and calcination?
Sintering generally refers to densification. When you sinter a powder, you generally start with a green body and heat it up with the intention of producing a dense, monolithic component. This contrasts with calcination where the goal is almost always to maintain discreet particles as a powder.
