CITIC Australia Iron Ore is the largest magnetite development and operation project in Australian mining history. The Australia Iron Ore project is located in the Pilbara region of Australia’s iron ore production belt, near Cape Preston, approximately 100 kilometers from the town of Kalgoorlie.
The project employs traditional open-pit mining techniques, utilizing specialized excavators to extract ore from the pit before transporting it to the processing plant for beneficiation. After undergoing fine grinding and separation, the ore is transformed into high-grade magnetic iron concentrate. Following thickening and dewatering, the concentrate is conveyed to the port for loading and export.
The CITIC Australia Mining Project’s mineral processing value-added segment places high demands on ore processing technology, mineral processing innovation, and labor. During project operations, local procurement in Western Australia is projected to exceed AUD 51 billion, creating substantial construction and operational roles related to magnetite processing. This will contribute to diversifying Australian workforce skills. The project directly employs 3,000 staff and contractors.
CITIC Magnetite Concentrate Production and Processing Flow
Through complex mineral processing techniques, CITIC’s Australian iron ore project transforms low-grade magnetite ore into high-purity magnetite concentrate with minimal impurities and an iron content as high as 65%. Pellets produced using this high-grade, low-impurity CITIC concentrate serve as an ideal furnace feedstock for steel production.
CITIC’s Australian mining project employs traditional open-pit mining techniques, involving drilling, blasting, and excavation of the pit. Simultaneously, specialized mining trucks transport the extracted ore to the pit crusher for primary crushing.
Magnetite ore is crushed into brick-sized pieces by an in-pit crusher, then transported via belt conveyor to the grinding mill production line at the mineral processing plant for grinding and separation. Here, the magnetite ore undergoes further crushing and grinding in large autogenous mills and ball mills to produce fine powder.
During grinding, magnetic separation is performed to stage-wise discard tailings, yielding high-grade magnetite concentrate.
The extracted magnetite concentrate is mixed with water to form a slurry, which is transported via a 30-kilometer pipeline to the dewatering workshop in the port area. After dewatering treatment, it is exported for shipment. The high-grade CITIC magnetite concentrate serves as an ideal furnace charge for steel production.
After dewatering, the magnetic concentrate is conveyed via belt to the finished product stockpile at the port, awaiting shipment. CITIC Australia Mining employs a transshipment model: ship loaders fill barges with magnetic iron concentrate at the port. The barges are then towed to deep-water areas, where transshipment vessels transfer the iron concentrate onto large ocean-going cargo ships. Additionally, CITIC Australia Mining utilizes self-propelled transshipment vessels (TSVs) for transshipment operations.
CITIC Australia Mining Public Utilities and Auxiliary Facilities
CITIC Australia Mining’s massive scale requires supporting infrastructure. To this end, the company has constructed its own power plant and water treatment facility to provide operational support for downstream large-scale mineral processing plants.
CITIC Australia Mine Power Plant employs combined-cycle power generation technology, incorporating a waste heat recovery system into its design. Compared to open-cycle power generation, this reduces greenhouse gas emissions by 40%. The plant comprises seven gas turbines, three steam turbines, and six waste heat boilers, with a total installed capacity of 480 MW. Its electricity output can meet the power demands of a large regional town.
CITIC Australia Mining’s seawater desalination plant employs traditional reverse osmosis membrane technology with a daily production capacity of 140,000 cubic meters. This not only meets the processing and operational demands of the concentrator but also provides potable water services to the port and dewatering workshop. By utilizing an energy recovery unit, the plant repurposes the brine that would otherwise be discharged to satisfy 50% of the pressure requirements for incoming seawater, thereby significantly reducing the energy consumption of the desalination process.
