The economy of Ghana has a diverse and rich resource base, including the manufacturing and exportation of digital technology goods, automotive and ship construction and exportation, and the exportation of diverse and rich resources such as hydrocarbons and industrial minerals. These have given Ghana one of the highest GDP per capita in West Africa. Owing to a GDP rebasement, in 2011 Ghana became the fastest-growing economy in the world.
The economy of Mali is based to a large extent upon agriculture, with a mostly rural population engaged in subsistence agriculture.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. These deposits form a mineralized commodity that is of economic interest to the miner.
The economy of Suriname was largely dependent upon the exports of aluminium oxide and small amounts of aluminium produced from bauxite mined in the country. However, after the departure of Alcoa, the economy depended on the exports of crude oil and gold. Suriname was ranked the 124th safest investment destination in the world in the March 2011 Euromoney Country Risk rankings.
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 the tantalite.
Gold mining is the extraction of gold resources by mining.
Nazi gold is gold possessed by Nazi Germany. Much of the focus of the discussion is about how much of this was transferred by Germany to overseas banks during World War II; the ruling Nazi party executed a policy of looting the assets of its victims to accumulate wealth, at least partly to finance the war efforts. Because gold stores are often private, exact details of transactions and storage are difficult to precisely identify. Gold that was collected was stored at least in part in central depositories. The transfer of gold in return for currency took place in collusion with many individual collaborative institutions. Although Swiss banks have been commonly identified as holding ill-gotten Nazi gold, the exact identities of the foreign banking institutions as well as the exact extent of the transactions remains unclear.
Galamsey, derived from the phrase "gather them and sell", is a local Ghanaian term which means illegal small-scale gold mining in Ghana. Such workers are known as galamseyers or orpailleurs in neighboring Francophone nations. Galamseyers are people who perform illegal gold mining independent of mining companies, digging small working pits, tunnels, and sluices by hand. Galamsey is also referred to as Illegal Artisanal Small Scale mining (ASM).
Prestea is a town in the Western Region, in southwest Ghana and about 50 km north of the coast of the Atlantic Ocean. It lies on the west bank of the Ankobra River, about 60 mi (100 km) northwest of Cape coast. The town is part of the Prestea-Huni Valley District. Prestea is the forty-sixth most populous in Ghana, in terms of population, with a population of 35,760 people. A railway line used to connects with Prestea to Tarkwa and beyond to the coastal city of Sekondi-Takoradi.
The Mining industry of Ghana accounts for 5% of the country's GDP and minerals make up 37% of total exports, of which 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, and, there are also over 300 registered small scale mining groups and 90 mine support service companies.
Gold Mining often plays a significant role in Burkina Faso’s economy. Burkina Faso has become Africa's 4th biggest producer of gold in 2012. Production of mineral commodities is limited to cement, dolomite, gold, granite, marble, phosphate rock, pumice, other volcanic materials, and salt.
Mineral industry of Colombia refers to the extraction of valuable minerals or other geological materials in Colombia. Colombia is well-endowed with minerals and energy resources. It has the largest coal reserves in Latin America, and is second to Brazil in hydroelectric potential. Estimates of petroleum reserves in 1995 were 3.1 billion barrels (490,000,000 m3). Colombia also possesses significant amounts of nickel and gold. Other important metals included platinum and silver, which were extracted in much smaller quantities. Colombia also produces copper, small amounts of iron ore, and bauxite. Nonmetallic mined minerals include salt, limestone, sulfur, gypsum, dolomite, barite, feldspar, clay, magnetite, mica, talcum, and marble. Colombia also produces most of the world's emeralds. Despite the variety of minerals available for exploitation, Colombia still had to import substances such as iron, copper, and aluminum to meet its industrial needs.
An artisanal miner or small-scale miner (ASM) is a subsistence miner who is not officially employed by a mining company, but works independently, mining minerals using their own resources, usually by hand.
Ghana gained independence from the British on 6 March 1957. It is a member of the Commonwealth of Nations. The country became a republic on July 1, 1960.
Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. Metals like zinc, copper, lead, aluminium as well as rare and noble metals are of particular interest in this field, while the more common metal, iron, is considered a major impurity. Like ferrous extraction, non-ferrous extraction primarily focuses on the economic optimization of extraction processes in separating qualitatively and quantitatively marketable metals from its impurities (gangue).
The London Conference on Nazi Gold was an international conference held in London in December 1997. Representatives of 41 nations participated in the Conference, including France, the United Kingdom, the United States, the three countries from the World War II Allies that fought Nazi Germany and the Axis powers that oversaw the post-War disposition of Nazi gold.
Mining has been practiced in Taiwan for hundreds of years. Sulfur was an early important resource collected on the island. Coal mining expanded in the 19th century to keep up with demand from increased foreign trade. Heavy industry was further expanded under Japanese rule, but air raids towards the end of World War II decimated mining infrastructure, falling below 19th century production levels. Copper mining expanded in the mid-20th century, but ended in the 1980s following a global collapse in the price of copper.
Tanzania is a land rich in minerals. Mining makes up more than 50% of the country's total exports, of which a large part comes from gold. The country has gold reserves of 45 million ounces, generating revenue of over a billion USD. Diamonds are also found in significant amounts. Since it was opened in 1940, the Williamson diamond mine has produced 19 million carats (3,800 kg) of diamonds. Gemstones, nickel, copper, uranium, kaolin, titanium, cobalt and platinum are also mined in Tanzania. Illegal mining and corruption are ongoing problems. In 2017, the government passed a series of bills aimed at increasing revenue from minerals after a scandal which caused the dismissal of the Minister for Energy and Minerals.
Illegal mining is mining activity that is undertaken without state permission, in particular in absence of land rights, mining licenses, and exploration or mineral transportation permits.
Ibrahim Mahama is a Ghanaian businessman, and the founder of Engineers and Planners, the largest indigenous-owned mining company in West Africa, and the owner of several other businesses in Ghana. He is the younger brother of John Dramani Mahama, President of Ghana from 2012 to 2017.
