Inrefining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than hascopper.In these operations some of thecopperis oxidized to cuprous oxide and dissolved by the metal bath.

Purecopper metalis generally produced from a multistageprocess, beginning with theminingand concentrating of low-grade ores containingcopper sulfide minerals, and followed by smelting and electrolytic refining to produce a purecopper cathode. An increasing share ofcopperis produced from acid leaching of oxidized ores.

Coppercan be found underground in the form ofcopperore. The maincopperore producing countries are Chile, theUnited States, Indonesia, Australia, Peru, Russia, Canada, China, Poland, Kazakhstan, Zambia, Zaire and Mexico. What HasCopperBeen Used for in the Past?Copperwas one of the first metals used by humans.
Nickel processing - Nickel processing -Extraction and refining: The extraction of nickel from ore follows much the same route ascopper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...
