There are two distinct categories of iron ore mining, surface mining such as open cast or strip mining and underground mining. At the surface iron ore processing plants, the iron ore is put through crushers and ball mills to break it into a uniform and more workable size and then washed with the residue going to tailings.

An improved experimental technique has been developed to measure, concurrently, the oxygen partial pressures and temperatures within a pilot scale iron ore sinter pot as a function of time. The measurements and thermodynamic calculations have demonstrated that the oxygen partial pressure at peak bed temperature and during cooling can be oxidising or reducing relative to hematite.

1. Introduction. Iron ore is an important strategic resource, and it is used extensively in a wide variety of fields. The steel and iron industries have developed rapidly in recent years, resulting in the requirement for a large quantity of iron ore [8,9].However, the decrease in high-quality iron ore resources is a serious threat to the sustainable development of the steel industry [21,25].

Iron and steel making by-products. As with all large-scale manufacturing processes, the production or iron and steel generates by-products. On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of by-products. The main by-products produced during iron and crude steel production are slags (90%), dusts and sludges.

The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13].Corresponding to each temperature interval, typical reactions will take place.
