Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine) These produce many millions of tonnes of copper ore per year
In 2012 Australia's mine production of copper totalled 914 kilotonne (kt) of contained copper 5% lower than in 2011 (961 kt) In 2012 SA surpassed Qld for a second year as the top copper producer with a total of 285 kt which was 9% less than in 2012 and represented 31% of all Australian production

The U S mining industry consists of the search for extraction beneficiation and processing of naturally occurring solid minerals from the earth These mined minerals include coal metals such as iron copper or zinc and industrial minerals such as potash limestone and other crushed rocks
In the United States the first copper mine was opened in Branby Connecticut in 1705 followed by one in Lancaster Pennsylvania in 1732 Despite this early production most copper used in the United States was imported from Chile until 1844 when mining of large deposits of high-grade copper ore around Lake Superior began
2 The Primary Copper Industry of Arizona in 1992 Copper was produced by 6 companies from 18 properties in 1992 and molybdenum was recovered as a co-product or by-product at 6 of these properties (Tables 3 and 4) Ten properties produced 98 0 percent of Arizona's copper and 3 produced 90 0 percent of the molybdenum
Mine an excavation made in the earth to extract minerals Mining the activity occupation and industry concerned with the extraction of minerals Mining engineering the practice of applying engineering principles to the development planning operation closure and reclamation of mines Some terms distinguish various types of mined minerals
For some business types there may be a similar industry to SIC Code 3339 - Primary Smelting and Refining of Nonferrous Metals except Copper and Aluminum that is a better classification match Establishments primarily engaged in rolling drawing and extruding these nonferrous primary metals are classified in SIC Code - 3356 and the production of bullion at the site of the mine is classified in SIC
This industry is comprised of 15 currently operating primary copper smelters 11 of which are integrated with primary mining and/or milling operations and 11 electrolytic refineries four of which are located on the same site with a primary smelter Seven electrolytic refineries are operated separately from the smelting operations
WATER REQUIREMENTS OF THE COPPER INDUSTRY By OBVILLB D MUSSEY ABSTRACT The copper industry in 1955 used about 330 million gallons of water per day in the mining and manufacturing of primary copper This amount is about 0 3 percent of the total estimated withdrawals of industrial water in the United States in 1955
These shafts get very hot and it's hard to breathe Rocks fall and sometimes gas explodes The deepest shaft mine is the TauTona gold mine in South Africa This mine is 2 4 miles deep Open pit mines are simply big open holes with terraced sides Coal copper and other minerals are dug out of the pits Very deep pits sometimes hold uranium
Copper in gemstones Copper is an important element in a number of gemstones such as turquoise azurite malachite and chrysocolla It gives these minerals their green or blue color and their high specific gravity The cabochons shown above are some of the many gemstones mined in Arizona
Primary smelters use mine concentrates as their main source of feed (although some use copper scrap as well) Secondary copper smelters use copper scrap (mainly low grade) as their feed Copper Smelter Production by Region 1997 (thousand tonnes)
Sep 28 2016We have recently undertaken a three-week research trip to China aimed at improving our understanding of Chinese copper mine costs and ensuring that the highest quality data is contained within CRU's Copper Mining Cost Model which uniquely provides coverage of the copper mining
