Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.

The concentration of low-grade iron ores is vital to the continued availability of iron and steel in our everyday lives (Eisele and Kawatra, 2003;Kawatra and Claremboux, 2021a;Zhang et al., 2021).
Iron Bridge. Iron Bridge signifies Fortescue's entry into the high grade segment of the iron ore market, providing an enhanced product range while also increasing annual production and shipping capacity. Located 145km south of Port Hedland, Iron Bridge is Fortescue's first magnetite operation and incorporates the North Star and Glacier ...
How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved ...
Slag formation in the grate-kiln process is a major problem for iron-ore pellet producers. It is therefore important to understand the slag formation mechanism in the grate-kiln production plant. This study initiated the investigation by in situ sampling and identifying particles in the flue gas from a full-scale 40 MW grate-kiln production plant for iron …
As evident in Fig. 1.2, the world's production of usable (processed) iron ore has increased from about 970 million tons in 2000 to 2.45 billion tons in 2019. Australia is the largest iron ore producing country, producing approximately 919 million tons of usable ore in 2019, equivalent to about 37% of the world's iron ore production.

In August 2022, the plant began shipping ore to steelmakers in the uncontrolled territories of Donetsk and Luhansk oblasts. The occupation administration has set a goal of increasing iron ore production at the plant to 3 million tons in 2023 and 5 million tons in 2025. Iron ore industry has faced problems that it had not faced before.
The production of high-quality sinter is crucial for assuring consistent, stable furnace productivity with a low consumption of reductants. Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption.
DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
