extraction of copper metal

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

copper extraction and purification

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas.

Extracting copper. Extracting copper.

Extraction: An ore has to be changed chemically into the metal. This process is called reduction. How this is done, and how much it costs, depends upon the metal's reactivity (see reactivity properties). In general, the more reactive the metal, the harder it is to extract it from its ore.
