  • lazare weiller

    lazare weiller 20 july 1858 – 12 august 1928 was a french engineer, industrialist and politician. he was born in alsace and received a technical education in england and in his cousin's copper factory in angoulême.he was very interested in the physical sciences, particularly the use of electricity to transmit sound and images.

  • coober pedy

    the copper-gold mine is operated by oz minerals. in august 2010 rann opened the cairn hill iron ore/copper/gold mine operated by imx resources near coober pedy. it was the first new iron ore mining area opened in south australia since the 19th century. due to low iron ore prices, the cairn hill mine was closed in june 2014.

  • swansea

    swansea became the ideal place to smelt the cornish copper ores, being close to the coalfields of south wales and having an excellent port to receive ships carrying cornish copper ore. because each ton of copper ore smelted used about three tons of coal, it was more economical to ship the copper ore to wales rather than send the coal to cornwall.

  • blue ledge mine

    the blue ledge mine is an inactive underground copper mine that has been classified as a superfund site by the environmental protection agency epa due to high concentrations of heavy metals. the mine is located approximately 3 miles south of the california–oregon border in the rogue river-siskiyou national forest.

  • copper in architecture

    the long lifetime of copper roofing and cladding has a significant positive effect on whole life assessments of copper versus other materials in terms of embodied energy consumption i.e., the total energy consumed during every phase of each lifecycle in mj/m 2 , co 2 generation, and cost.

  • adit

    the use of adits for the extraction of ore is generally called drift mining. adits can only be driven into a mine where the local topography permits. there will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. also if the ground is weak, the cost of shoring up a long adit may outweigh its possible .

  • industrial catalysts

    the disadvantage with a copper catalysts is that it is very sensitive when it comes to sulfide poisoning, a future use of for example a cobalt- molybdenum catalyst could solve this problem. the catalyst mainly used in the industry today is a copper-zinc-alumina cu/zno/al 2 o 3 based catalyst.

  • radioactive decay

    in principle a half-life, a third-life, or even a 1/ 2 -life, can be used in exactly the same way as half-life; but the mean life and half-life t 1/2 have been adopted as standard times associated with exponential decay. time-variable quantities: total activity— a, is the number of decays per unit time of a radioactive sample.

  • mechanical screening

    synthetic screen media typically rubber or polyurethane synthetic screen media is used where wear life is an issue. large producers such as mines or huge quarries use them to reduce the frequency of having to stop the plant for screen deck maintenance.
