Etoile Du Congo Mine
The Etoile Mine (also known as L'Etoile du Congo Mine, Kalukuluku, or Star of the Congo Mine) is an open-pit copper mine on the outskirts of Lubumbashi in Katanga Province of the Democratic Republic of the Congo (DRC). Chemaf (Chemical of Africa) owns the license. Chemaf is 95% owned by Shalina Resources and 5% by the DRC government. Location The Etoile mine is located at an elevation of about above sea level. The climate is sub-tropical, with annual rainfall of about falling mostly in the October to March period. Average temperatures are between and , with no marked difference between summer and winter. The region lies in a zone that would naturally be covered by Miombo Woodland, deciduous tropical woodlands. Lying on the edge of Lubumbashi, much of the woodland has been cleared. The Etoile orebody lies within the copperbelt that stretches from Luanshya in Zambia to Kolwezi in the DRC. As with many of the deposits in southern Katanga, it is a stratiform copper-cobalt deposi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Provinces Of The Democratic Republic Of The Congo
Article 2 of the Constitution of the Democratic Republic of the Congo divides the country into the capital city of Kinshasa and 25 named provinces. It also gives the capital the status of a province. Therefore, in many contexts Kinshasa is regarded as the 26th province. List History When Belgium annexed the Belgian Congo as a colony in November 1908, it was initially organised into 22 districts. Ten western districts were administered directly by the main colonial government, while the eastern part of the colony was administered under two vice-governments: eight northeastern districts formed Orientale Province, and four southeastern districts formed Katanga. In 1919, the colony was organised into four provinces: * Congo-Kasaï (five southwestern districts), * Équateur (five northwestern districts), * Orientale Province and Katanga (previous vice-governments).

Copper Mines In The Democratic Republic Of The Congo
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create b ...

Solvent Extraction Electrowinning
Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent. The copper is extracted from the solvent with strong aqueous acid which then deposits pure copper onto cathodes using an electrolytic procedure (electrowinning Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a ...). SX/EW processing is best known for its use by the copper industry, where it accounts for 20% of worldwide production, but the technology is also successfully applied to a wide range of other metals including cobalt, nickel, zinc and uranium.

Tanganyika Concessions
Tanganyika Concessions Limited (TCL or Tanks) was a British mining and railway company founded by the Scottish engineer and entrepreneur Robert Williams in 1899. The purpose was to exploit minerals in Northern Rhodesia and in the Congo Free State. Partly-owned subsidiaries included the '' Union Minière du Haut-Katanga'' (UMHK), which undertook mining in the Katanga portion of the copperbelt, and the Benguela railway, which provided a rail link across Angola to the Atlantic Ocean. Belgian banks eventually took over control of the company. The Angolan railway concession was returned to the state of Angola in 2001. Foundation and concessions Tanganyika Concessions Ltd. was created on 20 January 1899 by Robert Williams, an associate of Cecil Rhodes. Originally all the shareholders were British.

Haut-Katanga Province
Haut-Katanga (French for "Upper Katanga") is one of the 21 new provinces of the Democratic Republic of the Congo created in the 2015 repartitioning. Haut-Katanga, Haut-Lomami, Lualaba, and Tanganyika provinces are the result of the dismemberment of the former Katanga province. Haut-Katanga was formed from the Haut-Katanga district and the independently administered cities of Likasi and Lubumbashi. Lubumbashi retained its status as a provincial capital. The new province's territory corresponds to the historic Katanga-Oriental that existed in the early period after independence between 1963 and 1966. Territories Its current territories are: * Kasenga * Kipushi * Mitwaba * Pweto * Sakania Sakania is a town in Haut-Katanga Province, in the Congo Pedicle, in the far south of the Democratic Republic of Congo, near the border with Zambia. It is located at an elevation of 1278m asl, therefore it has a cool climate. Between 1935 and 1939 i ... Approximate correspondence between ...

Kolwezi
Kolwezi or Kolwesi is the capital city of Lualaba Province in the south of the Democratic Republic of the Congo, west of Likasi. It is home to an airport and a railway to Lubumbashi. Just outside of Kolwezi there is the static inverter plant of the HVDC Inga-Shaba. The population is approximately 573,000. Before the creation of Lualaba province in 2015 Kolwezi had two territories attached to it and the whole was known as the Kolwezi District. History The settlement was created in 1938 to be the headquarters for the western mining group of the ''Union Minière du Haut Katanga''. In 1971 it obtained city status and consisted of the communes of Dilala and Manika. In 1976 the territories of Lubudi and Mutshatsha, both previously part of Lualaba District, were attached to it to form the Kolwezi District (districts were called sub-regions at the time). In the 2015 repartitioning this was undone, the two territories and the city proper became separate parts of Lualaba province ...

Luanshya
Luanshya is a town in Zambia, in the Copperbelt Province near Ndola. It has a population of 117,579 (2008 census). Luanshya was founded in the early part of the 20th century after two prospector/explorer, William Collier shot and killed a Roan Antelope on the banks of the Luanshya River, discovering a copper deposit in the process. The antelope fell to the ground, its head resting on a rock where an exposed seam of copper ore was visible. The mining company eventually formed to exploit Collier's find was named " Roan Antelope Copper Mines Ltd". For most of the 20th century, copper was mined in great quantities at Luanshya but towards the end of the century, mining there became increasingly uneconomic, causing a severe recession in the town. There is still a fair amount of copper underground. Whether the town sees a revival in its fortunes will depend on how efficiently the copper is extracted and sold. The city is the birthplace of folk singer, John Edmond, writer A. C. Graylin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
