Union Minière Du Haut-Katanga
The ''Union Minière du Haut-Katanga'' (French language, French; literally "Mining Union of Upper-Katanga") was a Belgium, Belgian mining company (with minority British share) which controlled and operated the mining industry in the copperbelt region in the modern-day Democratic Republic of the Congo between 1906 and 1966. Created in 1906, the UMHK was founded as a joint venture of the Belgian Compagnie du Katanga, the Belgian Comité Spécial du Katanga and the British Tanganyika Concessions. The Compagnie du Katanga was a subsidiary of the Compagnie du Congo pour le Commerce et l'Industrie (CCCI), which was controlled by the countrhy's largest conglomerate, the Société Générale de Belgique. With the support of the Congo Free State, colonial state, the company was allocated a concession in Katanga Province, Katanga. Its primary product was copper, but it also produced tin, cobalt, radium, uranium, zinc, cadmium, germanium, manganese, silver, and gold. UMHK was part of a c ...

Copper
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 ...

World Copper Agreement Of 1935
The World Copper Agreement, signed March 28, 1935, was an agreement by mining companies that attempted to create a worldwide copper cartel. The agreement formally created the International Copper Cartel. Uniting African, South American and European producers, the agreement aimed to "bring about better conditions in the production, distribution and marketing of copper throughout the world outside of the United States" through curtailment of production. To supervise the implementation of the agreement and amend breaches of it, the agreement provided for the creation of a Control Committee of 5 members.

Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
Ruashi Mine
The Ruashi Mine is an open-pit copper and cobalt mine operated by Metorex that is located about from Lubumbashi in Katanga Province, Democratic Republic of the Congo. The project includes a plant to concentrate the ore from the Ruashi and Etoile mines, and a modern solvent extraction electrowinning (SX-EW) processing plant. As of 2008, annual capacity was estimated to be 10,000 tonnes of copper and 1,000 tonnes of Cobalt. Location The Ruashi 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. Tanganyika Concessions dug pits and trenches in the area in 1907. Union Minière du Haut Katanga (UMHK) dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Rhodesia
Northern Rhodesia was a British protectorate in southern Africa, south central Africa, now the independent country of Zambia. It was formed in 1911 by Amalgamation (politics), amalgamating the two earlier protectorates of Barotziland-North-Western Rhodesia and North-Eastern Rhodesia.''Commonwealth and Colonial Law'' by Kenneth Roberts-Wray, London, Stevens, 1966. P. 753 It was initially administered, as were the two earlier protectorates, by the British South Africa Company (BSAC), a chartered company, on behalf of the British Government. From 1924, it was administered by the British Government as a protectorate, under similar conditions to other British-administered protectorates, and the special provisions required when it was administered by BSAC were terminated.Northern Rhodesia Order in Council, 1924, S.R.O. 1924 No. 324, S.RO. & S.I.

Economy Of Europe
The economy of Europe comprises about 748 million people in 50 countries. The formation of the European Union (EU) and in 1999 the introduction of a unified currency, the Euro, brought participating European countries closer through the convenience of a shared currency and has led to a stronger European cash flow. It is important to note that the European Union is not a country, rather a unique global organisation, as an entity forming one of the largest economies in the world. The European Union also “regulates” the global market by the Single Market. The difference in wealth across Europe can be seen roughly in former Cold War divide, with some countries breaching the divide (Greece, Portugal, Slovenia, the Czech Republic, Slovakia, Lithuania, Latvia and Estonia). Whilst most European states have a GDP per capita higher than the world's average and are very highly developed, some European economies, despite their position over the world's average in the Human Deve ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.
