Mining industry of Sudan

Ancient historical records indicate that gold and iron mining in the country existed under the kingdom of Meroë and also during the reign of the kingdom of Nubia, the Pharaonic era, during the Roman period. The name 'Neb' in the Nubian language means "gold" and is attributed to the Nuba region. It was also called the "country of metal" by the British.[3]

Production from the mining sector accounts for about 4% of gross domestic product (GDP). Mineral extraction reported by the Government of Sudan include gold, chromium, gypsum, salt, and cement.[3] In 2012, the production of crude petroleum dropped to about 37.7 million barrels (Mbbl) from a high of 106.2 Mbbl in 2011 and 168.7 Mbbl in 2010.[1] Production of gypsum, feldspar, salt, gold, and cement have increased since 2012. Approximately 250,000 artisanal miners work in gold production.[1]

In the open pit Hassai Gold Mine, which has been under operation since 1993, gold production from 18 open pits was to the extent of 2.3 million ounces (Moz). The established reserve at this mine in the Proterozoic-aged Ariab greenstone belt is 14.09 million tons.[4]

The Minerals Development Act of 2007 and its regulations are in force. The Investment Promotion Law of 1999 and its amendments define the benefits that are available to the private companies to invest in the mining sector; agreements drawn cover both the exploration and mining phases. In the first instance, an Exploration Prospecting License is issued. Following a successful exploration of specific mines, a mining license is awarded to the company, with due registration of the production company under the Sudanese Companies Act 1925.[3]

Reserves of Phosphate found in Mount Kuoun and Mount Lauro in eastern Nuba, has been assessed as 400,000 tons, including some amount of uranium U 2 0 3.[3]

Kaolin, a clay mineral consisting of potassium and Aluminium silicate, is found in some areas of Khartoum and in the south of the River Nile State. Granite is extracted from the southern Wadi Halfa.[3]

Iron ore reserves lie in the Red Sea Mountains, in Mount Abu Tolo in South Kordofan, and in West Darfur and Baljrawih in River Nile State. The reserves found in the Baljrawih area and Wadi Halfa area have been assessed at 2 billion tons.[3]

Chromium deposits have been established in the Inqasna Mountains, the Nuba Mountains, and the Red Sea Mountains. The estimated reserves of crude chrome is 1 million tons. Chrome has been extracted since the 1970s.[3] Chromite is extracted from the Ingessana Hills, which has an estimated reserve of 1 million tons; production here in the recent years has been about 10,000 tons per year.[2] Manganese is found in the Red Sea Mountains and the Albeodh desert along the River Nile, and in areas around Khartoum State.[3]

Base metals like zinc, lead, aluminium, cobalt, and nickel found in the form of block sulfides are volcanic in nature. Zinc ore is assessed as 60 million tons in the Red Sea area. Lead is found in the Kutum area of North Darfur, aluminium in Darfur, cobalt in the Red Sea, and nickel in the Red Sea, Blue Nile, and South Kordofan.[3]

Uranium and rare earth elements have been found in Darfur pit copper, South and West Kurdufan, Red Sea, and Butana.[3]

Graphite has been located in the Blue Nile. Asbestos ore reserves in Inqasna have been assessed at 6,650 million tons, and asbestos fibers in the Gouge Zone Bees Reserve have the potential of 53,500 million tons, of which some has been mined.[3]

Tungsten reserves were assessed by the Bureau de Recherches Géologiques et Minières in 1981 in the Mount Ayub Ali area. The estimate of crude oil reserves was approximately 531,000 tons.[3] Gypsum has been identified in the Beraat region and in Mount Sagomhas, which has an estimated reserve of 34 million tons in the sea and 124 million tons at a depth of 50 metres (160 ft).[3]

Many gold extraction projects are expected to move to the production stage. However, constraints identified for such development are the large royalty fees, carriage costs, and governmental economic restrictions. Chromite mining is subject to demand in the world stainless steel sector.[1]
