Sintering: A Step Between Mining Iron Ore and Steelmaking
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

What Is Iron Ore Sintering? (with pictures)
11.05.2020 Iron ore sintering is a type of powder metallurgy used to pre-treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.

Sinter plant - Wikipedia
Sinter plants agglomerate iron ore fines (dust) 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 chemical ...

GOVERNMENT POLYTECHNIC DHANBAD
The principle of sintering involves the heating of iron ore fines along with flux and coke fines or coal to produce a semi-molten mass that solidifies into porous pieces of sinter with the size and strength characteristics necessary for feeding into the blast furnace. It is basically an agglomeration process achieved through combustion.
CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING
While magnetite, fayalite and glass containing iron oxides are the major mineral phases for siliceous sinter, the ferrites, magnetite and mixed calcium iron silicates are the major mineral phases for fluxed sinter. Sintering is a fast process and it is unlikely that equilibrium will be reached during sintering.
