extraction of copper from chalcopyrite
  • copper chemical industry

    about 80% of the world's primary copper comes from ores in which copper is present as a sulfide mineral, for example, chalcopyrite (cufes 2) (the most abundant copper ore), bornite (cu 5 fes 4) and chalcocite (cu 2 s). these ores contain typically only about 0.5 2% copper. the remainder of primary production comes from ores in which copper is

  • chalcocite (copper sulfide)

    chalcocite is an important copper mineral ore. it has been mined for centuries and is one of the most profitable copper ores. the reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur. it is not however the primary ore of copper due to its scarcity.
