A $20 billion iron ore project is set to start this year in Guinea's Simandou mountains after 27 years of delays. Rio Tinto, the Guinean government and at least seven other companies — including five from China — are partnering to work on what is widely considered to be the world's biggest mining project .
Abstract. Iron ore is regarded as the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trillion-dollar-a-year metal market and is the backbone of global infrastructure. To meet the growing demand for steel products, world iron ore production has increased ...

In recent years, some sources listed China as the largest producer of iron ore. However, this calculation was based on crude iron ore production. Since much of this crude ore production is low-grade and not usable, reliable sources discount it. As a result, China is the third-largest producer of usable iron ore.
