Iron Bridge is our magnetite mining operation, located 145km south of Port Hedland. Unlike our hematite operations, Iron Bridge produces a wet concentrate product which is transported to Port Hedland through a 135-kilometre-long specialist slurry pipeline where dewatering and materials handling occurs. It also includes a return water pipeline.

Iron ore obtained from hematite, magnetite, limonite or taconite is the key raw material for making iron and steel. Once mined, ore is cleaned and/or processed before being shipped to the blast furnaces. Since enor-mous volumes are needed and natural ores are extremely heavy, transporting it has become an industry in itself.
