To keep prices from taking a nosedive if there is a slowdown, as for example in the Chinese economy, a concentration of resources within 3 or 4 mining companies enable them to slow down development of new deposits to adjust supply with demand. In this case even if China slows, India, Russia and Brazil may still pick up, as they may be less sensitve to the U.S. consumer than China. China is a manufacturing export based economy compared to India and Russia, which are more dependent on internal demand. Iron ore prices have increased by three times since 2003, and China's imports of iron ore have gone up from 29% to half of the world's imports. Prices of all commodities copper, alumina, uranium have shot up. BHP and Rio both based in Melbourne, Australia have absorbed all the medium size companies in the Melbourne mining scene. Australia has traditionally been a leader in this field because of its huge mining resources. Other reasons for consolidation are the more complex technologies needed to develop the remaining deposit finds, which are fewer and fewer and of lesser quality. Another factor is that the resource nationalism in India, Bolivia, Indonesia, Mongolia and other places requires more sophisticated investors. Combining Rio and BHP also means BHP can use the better infrastructure of Rio and invest more productively in future infrastructure rail lines and port development to speed exports to other countries.
