The Ngwenya Mine is located on Bomvu Ridge, northwest of Mbabane and near the northwestern border of Eswatini (Swaziland). This mine is considered to be the world's oldest. The haematite ore deposit was used in the Middle Stone Age to extract red ochre, while in later times the deposit was mined for iron smelting and iron ore export.

Etymology

Ngwenya means "crocodile" in siSwati.^[1] This name comes from the fact that the mountains containing the mine was crocodile-shaped, before heavy-mining began in the 1960s and defaced this ancestral shape.^[2]

Background

Phase 1

Several stone age artefacts have been found in the mine during archaeological works in the late 1960s and early 1970s. Their age was established with radiocarbon dating as older than 20,000 years. Later, radiocarbon dating yielded the age of the oldest mining activities as 41,000 to 43,000 years.^[3] This would make Ngwenya the oldest known mine.^[4]^[5] The site was known to Early Man for its deposits of red and specular haematite, used in cosmetics and rituals.^[6]

Phase 2

Red ochre from here was extracted by the ancestors of the San and used in rock paintings, which are common in Eswatini. By about 400 AD, pastoralist Bantu tribes had been based there from the north of the Lepelle river. They were familiar with the smelting of iron ore, and traded their iron widely throughout the African continent.

Phase 3

The haematite iron ore with the iron content of up to 60% was prospected in the middle of the 19th century.^[7] The Swaziland Iron Ore Development Company (SIODC), owned by the Anglo-American Corporation, started mining of the deposit in 1964.^[7] A ten-year contract with a Japanese company made it the largest consumer of the iron ore. The open pit mining took place between 1964 and 1977, temporarily boosting the economic development of the area by establishing the Goba railway line connecting the mine with the Mozambique Railway System, and an electricity supply network (Matsapha industrial Site).^[4] An estimated 20,000,000 tonnes of iron ore have been extracted from the mine.^[8] However, an estimated 32 million tons of ore remained in the soil. Supposedly the Anglo-American Corporation stopped prospecting the mine because it got flooded.^[9]

There was a plan to revive extraction activities in the mine, but the price of iron ore fell, making the project hardly profitable. The land was eventually donated to the Swaziland National Trust Commission for management.^[10]

The mine's visitor center opened in 2005.^[1] The building was donated by the Republic of China on Taiwan, and some ancient tools displayed in the center were recovered with the help of the European Union.^[11]

In 2008, as the Swazi government was considering reopening the mine to extraction activities, the Swaziland National Trust Commission submitted the site to the UNESCO's list of World Heritage Sites to protect it, but the submission was not accepted.^[12]^[9] The inactive ancient mine is called the Lion Cavern. The modern-operations mine nearby is now flooded.^[1]

Phase 4

The Indian group Salgaocar operated the modern-day mine from 2011 to 2014 through the Salgaocar Swaziland Limited Company.^[9] Before allocating the mine to Salgaocar, the king Mswati III dismissed the National Trust Commission's request to protect the area from new mining activities, and replaced the entire board of the Commission to permanently stop those demands.^[13]

Those operations led to a heavy pollution of the water sources that feed the city of Mbabane. Among many environmental issues, the mining operations are a threat to Disa intermedia , a protected orchid growing exclusively in the region. Cases of corruption to get the mining license were reported, including a $28 million donation to the king by Salgaocar. The deal established a 25% ownership of the mine for the king, 25% for the government, and 50% to Salgaocar. Reports also claimed that Salgaocar was using Mozambican and South African trucks to avoid paying import taxes. 2,500 jobs were announced after the Salgaocar-Swazi deals, but the positions were never created.^[9]^[13] Salgaocar ceased its mining activities in Ngwenya in 2014.^[14]

In January 2018, the Mineral Management Board announced it was ready to relaunch prospecting activities at the Ngwenya mine.^[14]

In September 2018, the visitor center burnt to ashes. The National Trust Commission declared that all the ancient artifacts in the center were lost in the fire. The officers on site did not react when the fire started to spread.^[11]

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.

The Rammelsberg is a mountain, 635 metres (2,083 ft) high, on the northern edge of the Harz range, south of the historic town of Goslar in the North German state of Lower Saxony. The mountain is the location of an important silver, copper, and lead mine. When it closed in 1988, it had been the only mine still working continuously for over 1,000 years. Because of its long history of mining and testimony to the advancement and exchange of technology over many centuries, the visitor mine of Rammelsberg was inscribed as a UNESCO World Heritage Site in 1992.

Mining in the engineering discipline is the extraction of minerals from underneath, open pit, above, or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure.[citation needed]

Hhohho is a region of Eswatini, located in the north western part of the country.

The mining industry in India is a major economic activity which contributes significantly to the economy of India. The gross domestic product (GDP) contribution of the mining industry varies from 2.2% to 2.5% only but going by the GDP of the total industrial sector, it contributes around 10% to 11%. Even mining done on small scale contributes 6% to the entire cost of mineral production. Indian mining industry provides job opportunities to around 700,000 individuals.

<span class="mw-page-title-main">Mining industry of Nigeria</span>

The mining of minerals in Nigeria accounts for only 0.3% of its gross domestic product, due to the influence of its vast oil resources. The domestic mining industry is underdeveloped, leading to Nigeria having to import minerals that it could produce domestically, such as salt or iron ore. The rights to ownership of mineral resources is held by the Federal Government of Nigeria, which grants titles to organizations to explore, mine, and sell mineral resources. Organized mining began in 1903, when the Mineral Survey of the Northern Protectorates was created by the British colonial government. A year later, the Mineral Survey of the Southern Protectorates was founded. By the 1940s, Nigeria was a major producer of tin, columbite, and coal. The discovery of oil in 1956 hurt the mineral extraction industries, as government and industry both began to focus on this new resource. The Nigerian Civil War in the late 1960s led many expatriate mining experts to leave the country. Mining regulation is handled by the Ministry of Solid Minerals Development, who are tasked with the responsibility of overseeing the management of all mineral resources in Nigeria. Mining law is codified in the Federal Minerals and Mining Act of 1999. Historically, Nigeria's mining industry was monopolized by state-owned public corporations. This led to a decline in productivity in almost all mineral industries. The Obasanjo administration began a process of selling off government-owned corporations to private investors in 1999. The Nigerian Mining Industry has picked up since the "Economic Diversification Agenda", from Oil & Gas, to Agriculture, Mining, etc., began in the country.

Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining. A zinc mine is a mine that produces zinc minerals in ore as its primary product. Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals, such as gold, silver or copper. Mined ore is processed, usually on site, to produce one or more metal-rich concentrates, then transported to a zinc smelter for production of zinc metal.

The Husab Mine, operated under the Husab Uranium Project, is a uranium mine near the town of Swakopmund in the Erongo region of western-central Namibia. The mine is located approximately 5 kilometres (3.1 mi) south of the larger Rössing uranium mine and 45 kilometres (28 mi) from Walvis Bay. Swakop Uranium believes the Husab Mine has the potential to become the second largest uranium mine in the world after the McArthur River uranium mine in northern Saskatchewan, Canada and the largest open-pit mine on the African continent. Mine construction started in February 2013. The Husab Mine started production towards the end of 2016 after completion of the sulfuric acid leaching plant.
