Summary:
The Pilbara region comprises a large part of the ancient continental shield of Western Australia which is comprised of both Proterozoic and Archaean rocks. The Pilbara is overlain by the Proterozoics deposited in the Hamersley and Bangernall Provinces.
The BIF is a member of the ~620 m thick Brockman Iron Formation which makes up part of the 2.63 2.45 Ga Hamersley Group. The Hamersley Group comprises almost 2.5 km of consecutive sedimentary and volcanic rocks located within the ca. 80,000 km2 Hamersley Province of the Pilbara craton in North West Australia, approximately 1100 km north of Perth. In the lower part, it consists of dolomite, shale and BIF, while the upper part consists of dolerite, various lava types and BIF with minor amounts of tuffs and shales. Underlying the Hamersley Group, is the 2.78–2.63 Ga Fortescue Group, which consists of flood basalts and rhyolites. These volcanics were laid down on the uplifted and eroded Pilbara block. This volcanic succession may contain remnants of a Large Igneous Province (LIP).
The Brockman Iron Formation ofthe Hamersley Group is divided into four sub-lithostratigraphic units, namely the lowermost Dales Gorge Member (BIF), the Whaleback Shale Member, the Joffre Member (BIF), and the uppermost Yandicoogina Shale Member. After deposition, these laterally extensive BIF have all experienced minor folding and basinal uplift along with low-grade regional metamorphism – from burial prehnite–pumpellyite facies to greenschist facies.
General consensus exists regarding the depositional model of the Brockman Iron Formation. According to this model, the succession was deposited on a large, stable, and clastic-starved, continental platform, which was influenced by episodic inputs of fine-grained tuffaceous detritus.
Summary:
The Paraburdoo mine is located in the Pilbara region of Western Australia. The Paraburdoo mine, in combination with Eastern Range mine and the Western Range deposits, are known as the Greater Paraburdoo Iron Ore Hub.
Paraburdoo uses traditional open cut, conventional drill-and-blast and load-and-haul mining methods
to mine iron ore deposits positioned above and below the groundwater table.
Ore is processed on-site before being transported via rail to either Dampier or Cape Lambert ports for shipping.

Summary:
Iron ore from Paraburdoo and Channar mines is crushed and then processed through a central tertiary crushing and dry screening plant to produce a dry lump product, with further wet processing of the fines using hydrocyclones to remove slimes.
