Jun 11, 2019 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.

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 properties of the ingredients. The purpose of sinter are to be used converting iron into steel.

CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

A sinter feed with good permeability from ignition until burn-through is required for efficient operation of a sinter plant. In this regard it is necessary to consider the widely held and simplistic view that sinter feeds containing iron ores with high ultra-fines content have low-pre-ignition permeability.
