Top mining companies worldwide based on market value
Modern mining includes ore bodies which can harbor metal, coal, gemstone, and potash. Oil and gas extraction remains one of the most economically important sectors within mining operations. The mining industry exists on an important scale worldwide. Large mining companies tend to focus on mining production and operations to generate profit. London houses some of the most prominent mining companies, including BHP Billiton and Rio Tinto Group. Based on market capitalization in 2017, BHP Billiton, Rio Tinto, and China Shenhua Energy (China) were some of the top mining companies in the world. Originally headquartered in Australia, BHP Billiton’s revenue more than doubled between 2004 and 2014, growing from 24.9 billion to 56.8 billion U.S. dollars, but decreased to 30.9 billion U.S. dollars in 2016. Their primary focus is on metals and mining operations. Rio Tinto deals primarily with aluminum, iron ore, copper, uranium, coal, and diamonds. China Shenhua Energy is one of the largest government-owned mining corporations in the world. Some of its operations include coal mines, a railway network that is used to transport its coal, and power plants to generate and sell electricity.
Two of the world's largest gold mining companies are located in Canada. Barrick Gold and Goldcorp are both among the largest mining companies in the world with a respective market capitalization of 18.3 billion U.S. dollars and 11.2 billion U.S. dollars as of June 2017. However, gold producers from South Africa, the United States, Australia, and other countries are also among the global leaders in gold production based on 2016 values. Regulations have been formed in order to harmonize and stabilize the mining sector, especially within mineral-rich countries.
