The hypothetical open-pit mine described in table 7-2 uses an average of 20 million Btu of energy per ton of cathode copper produced, or about 21 percent of the energy consumed in pro-

  • Characteristics And Properties Of Copper And Copper Alloy

    Copper-lead alloys containing about 30 lead are stronger but have less satisfactory surface properties and are usually used with a thin lead-tin overlay. If the copper-lead alloys do not have sufficient load-carrying capacity, the lead content is reduced, and tin is added to improve the strength. Typical is a 74Cu-22Pb-4Sn composite.

  • Copper Motor Rotor Project

    Copper Motor Rotor. The use of copper for the conductor bars and end rings of induction motors in place of aluminum results in attractive improvements in motor energy efficiency. Until recently, die cast motor rotors were universally produced using aluminum because rotor fabrication by aluminum pressure die-casting was an established practice ...

Copper can be extracted from non-sulphide ores by a different process involving three separate stages Reaction of the ore over quite a long time and on a huge scale with a dilute acid such as dilute sulphuric acid to produce a very dilute copperII sulphate solution.

  • Uses Of Copper Supply Demand Production Resources

    Copper - A Metal Used Through The Ages. Copper was one of the first metals ever extracted and used by humans, and it has made vital contributions to sustaining and improving society since the dawn of civilization. Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age.
