The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It's a major ingredient in steel. Here's what the USGS has to say about iron ore:

Sinter Feed (6.3 mm - 0.150 mm): This is the most usual type of iron ore in the market. It is obtained at later stages of screening. In order to be fed into the blast furnace, the sinter feed must be agglomerated by and transformed into "sinter". The iron content of the CSN Mining sinter feed usually exceeds 63%. Pellet Feed (<0.150mm):

Sinter is one of the important inputs to Blast Furnace. Iron ore sintering process is dominating the agglomeration process in Steel manufacturing sector. To achieve good quality sinter, it is required to know the change in temperature with time for a particular segment of sinter bed. As sintering takes place in moving grate sinter machine this is difficult to achieve in real …

As an experimental sample, two sinter samples with significantly different hematite and magnetite ratios were prepared to compare their reduction behaviors. The reduction of wustite to iron was carried out at 1000, 900, and 800°C in a CO—CO 2 —H 2 atmosphere for the mineral morphology-controlled sinter, and the following findings were obtained.

Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.

Sinter is the main iron-containing raw material for blast furnaces. As iron ore resources are gradually depleted, the types of raw materials for sinter are complicated, so their chemical composition often changes. At present, the common method for studying the sintering performance of iron ore is the sintering pot test.

There are three major iron sources: pellets, sinter, and iron ore. Metallurgical coke is used as the fuel and reducing agent in the blast furnace process. Coke is the product of carbonization (or distillation) of mainly bituminous coal. Flux is also added to the blast furnace charge to absorb impurities present in the iron sources and coke ash.
