Specialization Operation Of Mining In Africa

In 1923, the british government exclusive concessions of theusa and south african mining territory granted groups over large areas inzambia (then northern rhodesian).Copper began in 1927 at the chambisi mine in "copperbelt province".Development of mining inzambia was on the agenda of the first years of colonization.The british south africa company in 1889 ceased to "extend the railway and telegraph network in the north to the zambezi river, to promote the migration and colonization and trade and mining concessions" to develop.Until 1923,zambia was maintained within the direct control of the company.This period created a large number of small businesses for prospecting and extraction.Many prospectors thoughtzambia was a secondsouth africa, with a wealth of precious metals, but soon had ambitions to copper exploitation limit.Therhodesia copper company was founded in 1902 and began the copper mines of kafue and bwana mkubwa develop.In 1920, two other companies that were associated with copper rhodesia exclusive mineral rights granted set up of the copper company venture from the british south africa on an area of 80,000 square kilometers, on the border with the belgian congo (zaire now is).Another mining company,tanganyika concessions already 1899 established mining rights inzambia was given by british south africa, andzaire by the king of the belgians.Founded in 1906, the company in cooperation with the belgian state, you the union miniere hautkatanga which much later was in thekatanga secession for the independence of thecongo.Two companies then out: rhodesian selection trust and rhodesian anglo american corporation, the zambian mines for more than 40 years were the control.In 1930, around 6,000 tonnes per year and until 1940 was 266,000 tonnes per year, the copper production inzambia.Copper mining decreased with the second world war but in the 1950s, the production of 280,000 to 568.000 tons per year increased.In the 1960s was much slower growth in the field of mining and copper output increased by 30% between 1960 and 1970.Here the production growth reflects the worldwide demand for copper, then very quickly increases tend to stabilize the.In the 1970s, the mining companies were copper production nationalized peaked at more than 750,000 tonnes per year achieved.Such a level should be achieved never again in the 1970s a decade that the crisis of copper marked specialisation inzambia despite huge reserves.In the early 1980's copper output was only approximately 550,000 tons.In many wayszaire was similar to that experience.As inzambia, the development of the mining industry had the basis of a colonization by financial capital since the beginning of the century led been.The first copper mills back until 1911 in lubumbashi.Invested in the 1930s, the belgian financial groups strongly in mining.But unlike inzambia, the copper mining inzaire grew relatively faster in the 1960s and 1970s, than it had in the 1940s and 1950s.237,000 to 500,000 tons copper output rose between 1958 and 1974.Between the wars, copper specialization in central and southern africa was already well developed, since about a fifth of world production, provided these areas until 1970, when she began to fall.Among other metallic minerals, chromium as important in this time, since africa was also provided one-fifth of world production.Iron year's production much later, during the 1950s and 1960s.As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing station.We also supply individual jaw crusher and raymond mill as well as spare parts of them.Jaw crusher:http://www.Hxjq-crusher.Com/1.Htmlraymond mill:http://www.Hxjq-crusher.Com/11.Html.
