In the extraction of copper from its sulphide ore when ore is subjected to roasting some of it is oxidised to cu 2 o which reacts with the remaining cu 2 s sulphide ore to give copper metalCu 2 s 2cu 2 o → 6cu so 2 ↑ in this process cu 2 s behaves as reducing agent.
Isolation of metal from the concentrated ore involves the refining of metals from the compounds it is found with to its original stateThe concentrated ore is first converted to an oxide after which metal extraction is done by reducing it from an oxide to metal using a suitable reducing agent.

Primary copper production begins with the extraction of copper-bearing ore by means of open-pit mining underground mining or leaching see diagram 1Copper ore is not usually exported since most of it is gangue which has no commercial value oecd 2015Ore is processed in one of two ways depending on whether it is oxide or sulphide ore.
Smelting and refining is the traditional approach used to recover the copper in the ore from the primary mineralized zoneBecause the smelting and refining process is expensive the copper sulfides in the ore are first concentrated into a copper sulfide concentrate by flotation techniques to provide a smaller volume of material for smelting.
