Iron ore
In 2020, we produced around 280 million tonnes of iron ore. That''s enough to make the steel for more than 3,300 Sydney Harbour Bridges. Our new South Flank mine in Western Australia will see its first production in 2021 and become one of the world’s largest iron ore operations, producing high-quality iron ore for around 25 years.

iron processing
Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is

Iron Ore Pelletization
Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.

Iron Production in the Viking Age
The iron ore shown to the right was excavated from Skógar, a Viking-age iron-making site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt.

Understanding US iron ore production | CRU
The fine particle size of the resulting iron ore concentrate is better suited to pelletising than sintering, which is why almost all US iron ore is pelletised. In fact, the physical properties of the local taconite deposits actually led Cleveland Cliffs to pioneer the iron ore pelletising process in the 1950s.
