Each mill measures about 12m in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

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.

Because iron and steelmaking at the time consumed more coal than iron ore, the steel mills moved closer to the coal mines to minimize transportation costs. A problem of coke was that it carried impurities such as sulfur, which degraded the quality of the steel. Although coke quickly became the dominant fuel for ironsmelting, in 1884 charcoal ...
