In 2004 alone it yielded about $12 billion of copper worth almost $800 million dollars on the market value when sold together with gold and silver valued at $70 million. The Bingham Canyon Mine's annual production rate is estimated at 300,000 tons (272,155 met ton) of copper, more than 10,000 ton (9070 met ton) of molybdenum, and …
Copper is extracted from its ore by a series of procedures, including mining, crushing, heating, chemically isolating impurities, refining, and purifying. Creating useful items from raw resources like copper ore requires a lengthy process but is possible with careful preparation and attention to detail.

(One organic substance, coal, is often discussed as a mineral as …
Copper is a chemical element; it has symbol Cu (from Latin 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 …
The resulting copper matte consisting of Cu 2 S is then roasted to change all sulfides into oxides. 2 Cu 2 S + 3 O 2 ---> 2 Cu 2 O + 2 SO 2. The cuprous oxide is converted to blister copper upon heating: 2 Cu 2 O ---> 4 Cu + O 2. This step exploits the relatively easy reduction of copper oxides to copper metal.
The copper areas on an enlarged photo-micrograph were outlined with a pencil in order to facilitate measurement. All measurements were carried out in duplicate. It took from 1.5 to 2 hours to measure the copper-areas of a photo-micrograph, the time varying with the clearness with which the edges of the eutectic were defined.

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
