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 ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total Fe content in the ore.

Steel production is a 24-hour-a-day, 365-day-a-year process, dependent on a consistent supply of raw materials and huge amounts of energy. According to the World Steel Association, world crude steel production has increased from 851 million tonnes (Mt) in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily increased from 150kg in 2001 to 225 kg in 2013.

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...

Steel production creates many byproducts including slag, dust, sludge, mill scale, iron oxide, iron sulphate, metal hydroxide sludge, ferric chloride, zinc, tar, benzene and sulphur (Blixt 2018). Many of these materials can be repurposed or reused in smelting other metals or sold to other industries like electronics production.
