es and 208 cars, carrying around 125 tonnes of ore each. The other runs from the Yarrie mine to Finucane Island. Trains on this line usually consist of just one locomotive pulling up to 90 cars .
Advanced technologies such as specialised computer software allow for all train movements to be controlled from a traffic control centre in Port Hedland. The rail systems also play a major role in the blending of ores. Ore is delivered to the ports in specific volumes and grades to ensure the ores are blended correctly to meet the grade requirements of the customer .
Mining and Processing
All of BHP Billiton Iron Ore's operations in the Pilbara use open pit mining methods. This involves conventional drilling and blasting of the ore which is then transported by haul trucks and put through the primary crusher. The primary crusher breaks down the ore into lumps approximately the size of a football. These lumps are then passed through a secondary crusher to produce lumps of ore that are about the sized of a grapefruit. The grapefruit-sized lumps are then sent to stockpiles to be loaded onto trains. Mt Whaleback also contains a beneficiation plant to remove any high grade ore from the contact waste 
Products
BHP Billiton Iron Ore's operations in the Pilbara produce eight different products, Newman Lump and Fines, Yandi Lump and Fines, Yarrie Lump and Fines and Mining Area C (MAC) Lump and Fines. The iron ore is transported to Port Hedland by rail and is exported to steelmakers in Japan, China, Taiwan, Korea, Europe and Australia. Nelson Point receives ore from Mt Whaleback, other Newman mines and Yandi, while ore from the Yarrie and Area C mines is sent to Finucane Island.

 
Discussion
Joint venture
In June 2009 BHP Billiton and Rio Tinto agreed to establish a production joint venture that would combine both of the companies' Western Australian iron ore assets.The joint venture will mean all current and future iron ore assets and liabilities will be owned 50:50 by the two companies. The joint venture between the two largest companies operating in the Pilbara will create an unrivalled and dominant iron ore business 
Due to the companies' overlapping resources, it is expected that the joint venture will reduce costs, add significant value and increase the efficiency of the operations. This is expected to be achieved by combining mines in close proximity into single operations, shorter rail hauls and providing greater blending opportunities to maximise recovery and operating efficiencies Iron ore produced during the joint venture will be split evenly between the companies' and sold independently. The ore will be sent in equal volumes to company designated ships for distribution. BHP Billiton is required to pay Rio Tinto US$5.8 billion at financial close for equity type interests to raise its interests in the joint venture to 50 per cent.

Conclusions
The Pilbara region is Australia's primary iron ore producing region, contributing to more than 96 per cent of iron ore exports. The joint venture between the two largest companies operating in the Pilbara, Rio Tinto and BHP Billiton, will provide the companies with cost reductions and significantly increase the efficiency of their operations. It also has the potential to create an unrivalled and dominant iron ore business t本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
