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.


Mining Methods

  • Truck & Shovel / Loader


Summary:

All of Hamersley Iron's mines are conventional open pits. Ore is loaded into haul trucks by shovels, hydraulic excavators or front-end-loaders, and transported to the primary crusher. It is then processed in a crushing and screening plant to produce fine ore and lump ore.


Crushing and Grinding


Processing

  • Dense media separation
  • Magnetic separation

Summary:

Transportation of ore to Tom Price mine for processing at a central processing facility via the existing overland conveyor. The existing haul road from Tom Price mine to S10 BRK, which runs parallel to the S10 overland conveyor, is the main access for heavy vehicles (including haulage of ore and transport of explosives).

Processed ore is transported from Tom Price mine via the existing Rio Tinto railway network to existing Rio Tinto port facilities located at Cape Lambert and Dampier. At Mount Tom Price, a high-grade plant produces lump product, fines and oversize. The low-grade ore feeds the concentrator, undergoes HMS and wet high intensity magnetic separation.
