Mining

Mining of gold, silver, copper, and oil was a major activity early on and remains so today. International mining companies became prominent in Britain in the 19th century, such as the Rio Tinto company founded in 1873, which started with the purchase of sulfur and copper mines from the Spanish government. Rio Tinto, now based in London and Melbourne, Australia, has made many acquisitions and expanded globally to mine aluminum, iron ore, copper, uranium, and diamonds. European mines in South Africa began opening in the late 19th century, producing gold and other minerals for the world market, jobs for locals, and business and profits for companies. Cecil Rhodes (1853–1902) was one of the few businessmen in the era who became Prime Minister (of South Africa 1890–1896). His mining enterprises included the British South Africa Company and De Beers. The latter company practically controlled the global diamond market from its base in southern Africa.
