Kamoto Mine
The Kamoto Mine (French language, French: ''La mine de Kamoto'') is an underground copper and cobalt mine to the west of Musonoi in the former Katanga Province, Democratic Republic of the Congo. the site is the largest active cobalt mine in the world. The mine includes the Luilu metallurgical plant, which accepts ore from KOV mine and Mashamba East, Mashamba East mine. The plant has polluted the Luilu River, and tailings also pollute the region with wind-blown dust. The Kolwezi tailings project, Kolwezi Tailings Project is an attempt to recover additional metal from these tailings. The exploitation rights are owned by the Kamoto Copper Company (KCC), a joint venture between Katanga Mining (75%) and the state-owned Gécamines (25%). Katanga Mining is now owned by Glencore. History Gécamines began operations in the Kamoto underground mine in 1969. The mine produced three million tonnes of ore annually in the 1980s. Before it closed in October 1990 it had produced 59.3 million to ... [...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).

Katanga Mining
Katanga Mining Ltd was a mining company operating in the Democratic Republic of the Congo with its headquarters in Canada. Katanga Mining operated a major mine complex in the Congo's Katanga Province, producing refined copper and cobalt. It claimed to have the "potential of becoming Africa's largest copper producer and the world's largest cobalt producer." Katanga Mining formed two joint-venture projects with state-owned Gécamines to develop the mining complex: Kamoto Copper Company (KCC) and DRC Copper and Cobalt Project (DCP). Assets and ownership The company was first listed on the Toronto Stock Exchange in August 1997. In January 2008 Katanga Mining acquired Nikanor plc for $452m. Katanga Mining was purchased by Glencore in 2020 and it was de-listed from the Toronto Stock Exchange. DRC Copper and Cobalt Project DRC Copper and Cobalt Project (DCP) began mining Tilwezembe, an open-pit copper and cobalt mine, in 2007. In November 2008, Katanga Mining said they had ...

Mining In Lualaba Province
Mining is the Resource extraction, 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 agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, 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 fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed.

Copper Mines In The Democratic Republic Of The Congo
Copper is a chemical element; it has Chemical symbol, symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductility, ductile metal with very high thermal conductivity, thermal and electrical conductivity. A freshly exposed surface of pure copper has a Copper (color), pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material#Metal, 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, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be Smelting, smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ...

Tilwezembe
Tilwezembe is an open-pit copper and cobalt mine in Lualaba Province of the Democratic Republic of the Congo owned by Katanga Mining, a subsidiary of Glencore. Officially, Glencore has shuttered the mine, but the site is still being used by artisinal miners. History The mine covers an area of . It has an indicated nine million tonnes of ore with 1.89% copper and 0.60% cobalt. Mining in the Tilwezambe pit has taken place off and on since 1999. At first this was done by the state-owned Gécamines using contract labor. In March 2004, Dan Gertler International and Beny Steinmetz Global founded a firm named Global Enterprises Corporate (GEC). In 2004 GEC and Gécamines agreed to rehabilitate and operate the Kananga and Tilwezembe mines. The deal was ratified by presidential decree. A joint venture of Katanga Mining (75%) and Gécamines (25%), named ''DRC Copper and Cobalt Project SARL'' (DCP SARL) began mining in 2007. In November 2008, Katanga Mining said they had temporarily susp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The resulting metals are said to be ''electrowon''. In electrowinning, an electrical current is passed from an inert anode through a ''leach'' solution containing the dissolved metal ions so that the metal is recovered as it is reduced and deposited in an electroplating process onto the cathode. In electrorefining, the anode consists of the impure metal (e.g., copper) to be refined. The impure metallic anode is oxidized and the metal dissolves into solution. The metal ions migrate through the electrolyte towards the cathode where the pure metal is deposited. Insoluble solid impur ...

Leaching (metallurgy)
Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within the ore, into soluble salts while the impurity remains insoluble. These can then be washed out and processed to give the pure metal; the materials left over are commonly known as tailings. Compared to pyrometallurgy, leaching is easier to perform, requires less energy and is potentially less harmful as no gaseous pollution occurs. Drawbacks of leaching include its lower efficiency and the often significant quantities of waste effluent and tailings produced, which are usually either highly acidic or alkali as well as toxic (e.g. bauxite tailings). There are four types of leaching: # Cyanide leaching (e.g. gold ore) # Ammonia leaching (e.g. crushed ore) # Alkali leaching (e.g. bauxite ore) # Acid leaching (e.g. sulfide ore) Leaching is also notable in the extraction of rare earth elements, which consists of lanthanides, yttrium and scandium. ...

Room Where Copper Is Electrolyzed At The Gecamines Luilu Refinery Near Kolwezi
In a building or a ship, a room is any enclosed space within a number of walls to which entry is possible only via a door or other dividing structure. The entrance connects it to either a passageway, another room, or the outdoors. The space is typically large enough for several people to move about. The size, fixtures, furnishings, and sometimes placement of the room within the building or ship (or sometimes a train) support the activity to be conducted in it. History Historically, the use of rooms dates at least to early Minoan cultures about 2200 BC, where excavations at Akrotiri on Santorini reveal clearly defined rooms within certain structures. In early structures, the different room types could be identified to include bedrooms, kitchens, bathing rooms, closets, reception rooms, and other specialized uses. The aforementioned Akrotiri excavations reveal rooms sometimes built above other rooms connected by staircases, bathrooms with alabaster appliances such as washbasi ...
