The Koodaideri deposit is located within the Hamersley Basin of Western Australia, the host to some of the most significant iron ore deposits in the world. Mineralisation at the Koodaideri deposit occurs as hematite-goethite within the Brockman Iron Formation and overlying detrital ores.

Conventional mining methods (truck and shovel) similar to other Rio Tinto Iron Ore mines were selected, and the mine has been designed to utilise in-pit crushing and conveying to transport ore to a central processing facility.

The Koodaideri Iron Ore Mine will produce 43 million tonnes per annum (Mtpa) of Saleable Ore Product (SOP) as lump and fines from coarse ore feed.

In order to process coarse ore feed into saleable ore product, the Koodaideri processing plant will include facilities for crushing, screening, stockpiling and loading onto rail transport.

Mobile crushing and screening units will be required to support mine earthworks. When constructed,the Koodaideri processing plant willoperate 24 hours perday, 7 days per week.

Run of Mine (ROM) ore will be delivered by haul truck to a primary gyratory crusher located to the north west of the K58W pit. The high-grade (HG) primary crushed ore will be processed through a dry crushing and screening plant to produce HG lump and HG fines product.

Seven double-deck banana screens will provide the required production throughput and achieve the required product specifications, which will divide the ore into three streams: lump product, fines product and oversize material.

Oversize material will be conveyed to the secondary crusher surge bin. The secondary crusher surge bin will have a total live capacity of 860 tonnes and incorporate two outlet hoppers, isolation gates and belt feeders, each providing feed to a cone secondary crusher. The design throughput of each secondary crusher is 3,600 tph.

The fines and lump products from the process plant will be conveyed to their respective fines and lump stockpiles. Representative samples of each ore stream are taken at six minute increments and sub-sampled prior to conveying directly to a fully automated laboratory cell. The laboratory cell will provide the metallurgical and analytical / chemical assays for the process. The laboratory will also manually process the mine and exploration samples with laboratory rejects conveyed back to the lump stockyard feed conveyor.

Finalproduct will be conveyed and stacked separately onto lump and fine product stockpiles for later reclaiming by a bucket wheel reclaimer to a train load-out (TLO) facility.
