Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
A gold rush or gold fever is a discovery of gold—sometimes accompanied by other precious metals and rare-earth minerals—that brings an onrush of miners seeking their fortune. Major gold rushes took place in the 19th century in Australia, Greece, New Zealand, Brazil, Chile, South Africa, California, the United States, and Canada while smaller gold rushes took place elsewhere.
Placer mining is the mining of stream bed (alluvial) deposits for minerals. This may be done by open-pit or by various surface excavating equipment or tunneling equipment.

The Mineral Revolution is a term used by historians to refer to the rapid industrialisation and economic changes which occurred in South Africa from the 1860s onwards. The Mineral Revolution was largely driven by the need to create a permanent workforce to work in the mining industry, and saw South Africa transformed from a patchwork of agrarian states to a unified, industrial nation. In political terms, the Mineral Revolution had a significant impact on diplomacy and military affairs. Finally, the policies and events of the Mineral Revolution had an increasingly negative impact on race relations in South Africa, and formed the basis of the apartheid system, which dominated South African society for a century. The Mineral Revolution was caused by the discovery of diamonds in Kimberly in 1867 and also by the discovery of gold in Witwatersrand in 1886. The mineral mining revolution laid the foundations of racial segregation and the control of white South Africans over black South Africans. The Mineral Revolution changed South Africa from being an agricultural society to becoming the largest gold producing country in the world.

The Mining industry of Ghana accounts for 5% of the country's GDP and minerals make up 37% of total exports. Gold contributes over 90% of the total mineral exports. Thus, the main focus of Ghana's mining and minerals development industry remains focused on gold. Ghana is Africa's largest gold producer, producing 80.5 t in 2008. Ghana is also a major producer of bauxite, manganese and diamonds. Ghana has 20 large-scale mining companies producing gold, diamonds, bauxite and manganese; over 300 registered small scale mining groups; and 90 mine support service companies. Other mineral commodities produced in the country are natural gas, petroleum, salt, and silver.
The second-largest mineral industry in the world is the mineral industry of Africa, which implies large quantities of resources due to Africa being the second largest continent, with 30.37 million square kilometres of land.With a population of 1.4 billion living there, mineral exploration and production constitute significant parts of their economies for many African countries and remain keys to economic growth. Africa is richly endowed with mineral reserves and ranks first in quantity of world reserves for bauxite, cobalt, industrial diamond, phosphate rock, platinum-group metals (PGM), vermiculite, and zirconium.
The Sunrise Dam Gold Mine is located 55 km south of Laverton, Western Australia, on the eastern margin of Lake Carey. It is fully owned by AngloGold Ashanti and comprises a large-scale mechanized underground mine with a conventional gravity and leach process plant.

The Birimian rocks are major sources of gold and diamonds that extend through Ghana, Côte d'Ivoire, Guinea, Mali and Burkina Faso. They are named after the Birim River, one of the main tributaries of the Pra River in Ghana and the country's most important diamond-producing area. Ghana and Mali are the second and third largest producers of gold in Africa, respectively.
The Birim River is one of the main tributaries of the Pra River in Ghana and the country's most important diamond-producing area, flowing through most of the width of the Eastern region. The river rises in the east of the Atewa Range, flows north through the gap between this range and the Kwahu Plateau, then runs roughly south-west until it joins the Pra. It gives its name to the Birimian rock formation, which yields most of the gold in the region. Ghana is the second largest producer of gold in Africa.
The Obuasi Gold Mine is an underground gold mine situated near Obuasi, in the Ashanti Region of Ghana. It was at one time one of the world's ten largest gold mines. The mine is in Obuasi Municipal District, 60 kilometres (37 mi) southwest of the regional capital Kumasi.
The Société d'Exploitation des Mines d'Or de Sadiola S.A (SEMOS) project is an open-pit gold mine situated near Sadiola, in the Kayes Region of Mali. The mine was discovered based on the fieldwork of Canadian geologist James C. Snell P. Eng., on behalf of IAMGOLD founder Mark Nathanson. Nathanson took credit for the rich discovery, leaving Snell to fend off an assassination attempt on the streets of London England days after giving his geological report to Nathanson and financiers without payment. After years of seeking justice, Snell committed suicide in east Vancouver Canada. Nathanson became a philanthropist giving a large sum of money to York University in Toronto Canada. Sadiola was jointly owned by AngloGold Ashanti and IAMGOLD, who each had an effective holding of 41%, while the Government of Mali owned the remaining 18%. The International Finance Corporation originally held 6% of the mine put sold this share equally to AGA and IAMGOLD in December 2009.
