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.
Coltan is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite, and the tantalum-dominant mineral is tantalite.
Pointe-Noire is the second largest city in the Republic of the Congo, following the capital of Brazzaville, and an autonomous department and a commune since the 2002 Constitution. Before this date it was the capital of the Kouilou region. It is situated on a headland between Pointe-Noire Bay and the Atlantic Ocean. Pointe-Noire is the main commercial centre of the country and has a population of 1,420,612 inhabitants in 2023.
The Congo–Ocean Railway links the Atlantic port of Pointe-Noire with Brazzaville, a distance of 502 kilometres (312 mi). It bypasses the rapids on the lower Congo River; from Brazzaville, river boats are able to ascend the Congo River and its major tributaries, including the Oubangui River to Bangui.
The COMILOG Cableway was one of the longest cableways in the world, until its closure in 1986. The ropeway conveyor ran for 76 km from Moanda in the Haut-Ogooué Province of south eastern Gabon to Mbinda in the Republic of Congo.
Iron ore production in Africa is dominated by South Africa, Mauritania and Algeria. Many countries possess iron ore deposits that are as yet untapped/unmined. Countries and companies currently involved in production are listed here; measurements are in tonnes per annum(year).
Eurasian Natural Resources Corporation PLC (ENRC) was a public, Kazakhstan/Central African-focused, multinational leading diversified natural resources company headquartered in London, United Kingdom. It had activities in integrated mining, processing, energy, logistics and marketing.
The mining industry of the Democratic Republic of the Congo produces copper, diamonds, tantalum, tin, gold, and more than 63% of global cobalt production. Minerals and petroleum are central to the DRC's economy, making up more than 95% of the value of its exports. According to a 2011 report the total value of the major mineral reserves in the DRC amounted to a total of over 300 billion US dollars at the time. The mining industry in the DRC mainly consists of private, large industrial mines, semi-industrial, and artisanal mines. While private sectors take on large operations, they rely heavily on artisanal mining for extraction of resources. These industries along with non-for-profit organizations are continuously changing their guidelines as the DRC becomes more and more desirable for their valuable minerals. Mining in the DRC took place beginning in the 14th century and is still very present today, with mass scale lootings halting many major projects. The main countries involved in the mining operations in the DRC are Canada and China along with 25 other international mines active in the area. While technological companies strive for sustainable production and consumption of their products using cobalt, this is often achieved by the work of artisanal mining in hazardous and unjust working conditions. The process of mining and extraction in any area has negative impacts on the environment and those living in it, however, the DRC has faced many acts of environmental injustice including child labor under fatal conditions, exploitation of laborers, and displacement.
Mining is important to the economy of Ethiopia as a diversification from agriculture. Currently, mining comprises only 1% of GDP. Gold, gemstones, and industrial minerals are important commodities for the country's export-oriented growth strategy.
Despite being a mineral rich country, Cameroon has only recently begun to investigate mining on an industrial scale. Strong metal and industrial mineral prices since 2003 have encouraged companies to develop mines here. The terrain mainly consists of granite-rich ground with areas of ultramafic rocks that are sources of cobalt and nickel. There are also deposits of bauxite, gold, iron ore, nepheline syenite, and rutile. Alluvial gold is mainly mined by artisanal miners.
Railway stations in the Republic of the Congo (Congo) include:
Africa has a large quantity of natural resources, including diamonds, sugar, salt, gold, iron, cobalt, uranium, copper, bauxite, silver, petroleum, natural gas and cocoa beans, but also tropical timber and tropical fruit.
Sundance Resources Limited is an Australian mining company, based in Perth, Western Australia, whose main assets are iron ore leases in Cameroon near Mbalam, and across the border in the Republic of Congo. Following the loss of the Congo mining licence in 2020, Sundance Resources delisted from the Australian Securities Exchange and sued Congo to acquire $8.76 billion in compensation.
Hanlong Group (汉龙集团) is a Chinese conglomerate with holdings in solar energy, communications, chemicals, mineral exploration, and other industries.
Cominco Resources is a private company which is developing the US$2billion Hinda phosphate project located in The Republic of the Congo. Through its subsidiary it owns 100% of the Hinda Phosphate Project, which comprises the Hinda Permit, and the Kolatchikanou Permit. The Hinda project is the world's largest undeveloped phosphate deposit with a JORC Mineral Resource of 678 Mt and a Minable Ore Reserve of 405 Mt, sufficient for over 24 years of production. Cominco Resources was merged with Kropz in December 2018 and listed on the AIM market.
The mining industry of Yemen is at present dominated by fossil mineral of petroleum and liquefied natural gas (LNG), and to a limited extent by extraction of dimension stone, gypsum, and refined petroleum. Reserves of metals like cobalt, copper, gold, iron ore, nickel, niobium, platinum-group metals, silver, tantalum, and zinc are awaiting exploration. Industrial minerals with identified reserves include black sands with ilmenite, monazite, rutile, and zirconium, celestine, clays, dimension stone, dolomite, feldspar, fluorite, gypsum, limestone, magnesite, perlite, pure limestone, quartz, salt, sandstone, scoria, talc, and zeolites; some of these are under exploitation.
The Compagnie minière de l'Ogooué, or COMILOG, is a manganese mining and processing company based in Moanda, Gabon. It is a subsidiary of the French metallurgical group Eramet. The company is the world's second largest producer of manganese ore. At first the ore was carried by a cableway to the border with the Republic of the Congo, then by rail to the sea at Pointe-Noire. In the 1980s a railway was built to carry the ore through Gabon to the sea near Libreville.
The geology of the Republic of the Congo, also known as Congo-Brazzaville, to differentiate from the Democratic Republic of the Congo, formerly Zaire, includes extensive igneous and metamorphic basement rock, some up to two billion years old and sedimentary rocks formed within the past 250 million years. Much of the country's geology is hidden by sediments formed in the past 2.5 million years of the Quaternary.
