Iron ore processing by Rio Tinto in the Pilbara region of Western Australia does not involve any chemical treatment. Flowsheets for the Brockman 2 and Paraburdoo processing plants are given in Figures 8.4 and 8.5 (Kinnel, 2013). The flowsheets are relatively simple. Dry processing involves up to three crushing circuits to produce lump and fines.

Wickham was constructed as recently as 1970 by Cliffs Robe River Iron Associates. The aim was to create a processing plant for the iron ore mined at Pannawonica, a port at Cape Lambert from which to ship the ore, and a town to house the workers. Today Wickham is a vibrant mining community with a wide range of amenities.

In general, iron ore is mixed with coke in a blast furnace, the coke is burned while oxygen is blown in. There are other materials added too. The slag is separated from the iron. The iron is poured onto forms. In this state it is called pig iron. From here it is made into cast iron or steel.

Q. Blast furnace operation, FINEX, and Hydrogen-based Steelmaking. How are they different? A. In the blast furnace operation, iron ore and coal are first processed at the sintering plant and coke plant into appropriate states, respectively, and then go into the blast furnace.The blast furnace produces molten iron, which is then put back into the converter to make them into molten steel.

Also, How is iron ore transported from the mines to the port? All the iron ore that is mined is then processed in our processing plants. There the ore is dressed and concentrated, before finally being pelletised, i.e. heated to form small, round balls. From the processing plants, the iron ore products are transported by rail to the ports.

Taconite is a low-grade iron ore. Originally thought to be of little value, taconite was considered overburden (waste) in the days when high grade iron ore was mined. The iron content, magnetite, is only 20- 30% compared to 50 - 60 % iron content in red ore. Red ore is also referred to as direct shipped ore because it can be shipped without processing.

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.

Crushed ore is divided into various fractions by passing it over sieves through which undersized material falls. In this way, lump or rubble ore (7 to 25 millimetres in size) is separated from the fines (less than 7 millimetres). If the lump ore is of the appropriate quality, it can be charged to the blast furnace without any further processing.
