"}" id="mwjg"> [12] ) did take issues of environmental impact into consideration when building. [13] It is said that this particular mine holds about 60,000,000 carats (12,000 kg) worth of reserves. [14] Other mines, however, were not designed to reduce environmental impacts. Aside from removing of massive amounts of land for mining purposed, the practice also leaches the soil of nutrients when diamond extraction takes place.
Pipe mining affects the local flora through road-building; forests are disrupted when machinery uproots trees to make roadways to the mines. It is estimated that about one ton of earth must be removed in order to produce less than 1 carat (0.20 g), and that soon the Catoca diamond mine will produce up to 5,000,000 carats (1,000 kg) annually, which will translate to almost 10,000,000,000 lb (4.5×109 kg) of earth removed each year. Once land is disrupted in this way, it is very difficult for vegetation to re-grow. [15]
Water quality is negatively affected by alluvial mining. Many rivers are diverted so that mines can be exposed; canals are created and short sections of the river are dammed. [15] Although rivers can be returned to their natural state after mining, they are typically abandoned and left in the same condition they were in when they were in production. Soil deposits affect water quality as the land is unearthed. The water becomes clouded by sediment, polluting drinking water for animals. Oil and chemicals from the pipe mines seep into the ground and into the water supply.
In places where water is already scarce, it is important to keep the water they do have in good drinkable condition.
Many environmental policies have been enacted over the past two decades due to the threat that mining poses to ecosystems and biodiversity in many regions in the world. Angola is located in one of the five most threatened hotspots in the world. The Congolean forest that is being endangered due to poor mining practices [16] Agenda 21: 1992 Earth Summit asked transnational companies to reduce environmental damage and developed countries to begin sustainable consumption. [16] Convention on Biological Diversity: Articles that were created to prevent and respond to activities and impacts that threaten biodiversity. [16] Intergovernmental Panel on Forests: National forest program that addresses industrial development, agriculture, and energy to avoid bad policy choices that could affect forests negatively such as mining. [16] Berlin Guidelines: UN Department of Technical Co-operation for Development, stresses environmental stewardship in mining. [16] UNCTAD: A project that integrates mining activity with planning for a sustainable future. [16]
Due to Angola's vast quantity of natural resources, its GDP is currently growing at a rate of 16.3%. [17] The growth that has occurred is due to the civil war finally being over, which has allowed American companies to come here to the country to set up oil drills and open new diamond mines. [5] But the economic growth of the country is not spreading to stimulate development in the population 65% of whom live on one dollar a day. [17] There are also millions of refugees and former Unita and MPLA soldiers living in camps across the country with malaria and dysentery widespread. [6]
To provide sustainable jobs and income for the millions of displaced Angolan people will involve developing agriculture and industry that does not rely on non-renewable resources. [5] The price of diamonds dropped after large mines opened in Russia and China. Oil is not owned by the people, with uneven allocation of funds occurring between politicians and oil companies. [5] Angola has large rivers and delta regions, which potentially could be dammed to create electricity for export to neighboring countries. [5]
Once a major export, iron ore was no longer being mined in Angola by the late 1980s, because of attendant security and transportation problems. From the mid-1950s to 1975, iron ore was mined in Malanje, Bié Province, Huambo, and Huíla provinces, and production reached an average of 5.7 million tons per year between 1970 and 1974. Most of the iron ore was shipped to Japan, West Germany, and Britain; it earned almost US$50 million a year in export revenue. After independence, the government established a state company, the National Iron Ore Company of Angola (Emprêsa Nacional de Ferro de Angola—Ferrangol), for exploration and mining, processing, and marketing of iron ore. Ferrangol contracted with Austromineral, an Austrian company, to repair its facilities and organize production in Cassinga in Huíla Province. Production began to slow in 1974 as a result of technical problems at the Cassinga mine and stopped completely in August 1975. The area fell under foreign control when South African forces invaded in 1975. Although South Africa withdrew its troops in early 1976, as of 1988 mining had not resumed in the area. [18]
By 1988 the Cassinga mines had a production capacity of approximately 1.1 million tons per year. However, the railroad to the port of Moçâmedes (then called Namibe) needed extensive repair, and since it was located only 310 kilometers north of the Namibian border, security against South African attacks could not be ensured. Furthermore, UNITA was active in the area and posed a threat to the rail line if it were repaired. Even supposing these problems could be resolved, production of iron ore at Cassinga would be costly in view of the depressed state of the world steel market in the late 1980s. [18]
Angola is also rich in several other mineral resources that had not been fully exploited by the early twenty- first century . These include manganese, copper, gold, phosphates, granite, marble, uranium, quartz, lead, zinc, wolfram, tin, fluorite, sulfur, feldspar, kaolin, mica, asphalt, gypsum, and talc. The government hopes to resume mining in the southwest for crystalline quartz and ornamental marble. It has been estimated that 5,000 cubic meters of marble could be extracted annually for a period of twenty years. A state-owned company[ who? ] mined granite and marble in Huíla and Namibe Provinces, and in 1983 it produced 4,450 cubic meters of granite and 500 cubic meters of marble. Since then, the company has ceased production in order to re-tool with modern machinery. Quartz production, however, was suspended indefinitely because of the military situation in areas near the extraction sites in Cuanza Sul Province. [19]
The government established a company in 1980 to exploit phosphate deposits in the northwest. There were 50 million tons of deposits in Zaire Province and about 100 million tons in Cabinda. Although studies of the deposits in both locations have been made by Bulgarian and Yugoslav companies, as of 1988 production had not started at either site. [19]
The economy of Angola remains heavily influenced by the effects of four decades of conflict in the last part of the 20th century, the war for independence from Portugal (1961–75) and the subsequent civil war (1975–2002). Poverty since 2002 is reduced over 50% and a third of the population relies on subsistence agriculture. Since 2002, when the 27-year civil war ended, government policy prioritized the repair and improvement of infrastructure and strengthening of political and social institutions. During the first decade of the 21st century, Angola's economy was one of the fastest-growing in the world, with reported annual average GDP growth of 11.1 percent from 2001 to 2010. High international oil prices and rising oil production contributed to strong economic growth, although with high inequality, at that time. 2022 trade surplus was $30 billion, compared to $48 billion in 2012.
Angola was first settled by San hunter-gatherer societies before the northern domains came under the rule of Bantu states such as Kongo and Ndongo. In the 15th century, Portuguese colonists began trading, and a settlement was established at Luanda during the 16th century. Portugal annexed territories in the region which were ruled as a colony from 1655, and Angola was incorporated as an overseas province of Portugal in 1951. After the Angolan War of Independence, which ended in 1974 with an army mutiny and leftist coup in Lisbon, Angola achieved independence in 1975 through the Alvor Agreement. After independence, Angola entered a long period of civil war that lasted until 2002.

The Catoca diamond mine is the fourth largest diamond mine in the world, and is located in Angola. The mine is located on a kimberlite pipe. The mine is owned by a joint venture between the Angolan state-owned company Endiama, and the Russian company Alrosa.
The Williamson Diamond Mine is a diamond mine 23 kilometres (14 mi) northeast of Shinyanga in Tanzania; it became well known as the first significant diamond mine outside of South Africa. The kimberlite pipe was found in March 1940 and the mine established by John Williamson, a Canadian geologist, and has been continuous operation since then, making it one of the oldest continuously operating diamond mines in the world. Over its lifetime it has produced over 19 million carats (3,800 kg) of diamonds. A 2020 report by The Guardian said that high-quality pink diamonds from the mine could value up to $700,000 a carat.
Dundo, or Dundo-Chitato, is a former mining town, with a population of 177,604 (2014), now a city and the provincial capital of Lunda Norte in Angola. Established in the early part of the 20th century as a planned diamond mining community, Dundo has continued to grow, has its own airport and is now being superseded by a new city, New Dundo.
ENDIAMA E.P. is the state-run national diamond company of Angola. It is the exclusive concessionary of mining rights in the domain of rough diamonds in Angola.
Cassinga or Kassinga is a town and commune in the municipality of Jamba, province of Huíla, Angola.
Angola and the United States have maintained cordial diplomatic relations since 1993. Before then, antagonism between the countries hinged on Cold War geopolitics, which led the U.S. to support anti-government rebels during the protracted Angolan Civil War.
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 mining sector of Ivory Coast contributes to 13% of the country's exports annually and accounts for 5% of the GDP. The industry has historically centered on the extraction of gold. Although the subsoil of Ivory Coast contains many other minerals, none had been discovered in commercially exploitable amounts.
In the 1920s in Angola mining became the primary source of revenue for the colonial government.
The Central African Republic's mineral resource endowment includes copper, diamond, gold, graphite, ilmenite, iron ore, kaolin, kyanite, lignite, limestone, manganese, monazite, quartz, rutile, salt, tin, and uranium. Of these commodities, only diamond and gold were produced in 2006 - subsistence farming was the mainstay of the economy.
The Companhia de Diamantes de Angola (Diamang) was a company exploiting diamond mines in Angola. Diamang was formed on 16 October 1917 by financial investors from Angola's then colonial master Portugal, and also from Belgium, United States, Great Britain and South Africa. The company was formally dissolved on 17 February 1988.
In southwestern Africa, Portuguese Angola was a historical colony of the Portuguese Empire (1575–1951), the overseas province Portuguese West Africa of Estado Novo Portugal (1951–1972), and the State of Angola of the Portuguese Empire (1972–1975). It became the independent People's Republic of Angola in 1975.
The mining industry of Sierra Leone accounted for 4.5 percent of the country's GDP in 2007 and minerals made up 79 percent of total export revenue with diamonds accounting for 46 percent of export revenue in 2008. The main minerals mined in Sierra Leone are diamonds, rutile, bauxite, gold, iron and limonite.
The mining industry of Guinea was developed during colonial rule. The minerals extracted consisted of iron, gold, diamond, and bauxite. Guinea ranks first in the world in bauxite reserves and 6th in the extraction of high-grade bauxite, the aluminium ore. The mining industry and exports of mining products accounted for 17% of Guinea's gross domestic product (GDP) in 2010. Mining accounts for over 50% of its exports. The country accounts for 94% of Africa's mining production of bauxite. The large mineral reserve, which has mostly remained untapped, is of immense interest for international firms.
The mining industry of Liberia has witnessed a revival after the civil war which ended in 2003. Gold, diamonds, and iron ore form the core minerals of the mining sector with a new Mineral Development Policy and Mining Code being put in place to attract foreign investments. In 2013, the mineral sector accounted for 11% of GDP in the country and the World Bank projected a further increase in the sector by 2017.
The Sociedade de Comercialização de Diamantes, in English the Diamond Trading Society, is the national diamond trading company of Angola. It is owned in part by ENDIAMA and exists to bring diamonds produced both through ENDIAMA's partnered mines and by artisanal miners to national and international markets.
