Copper Smelting Chemistry Tutorial AUS e TUTE

Any copper I oxide present will be converted into copper I sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen for example Cu 2 O FeS → Cu 2 S FeO Impurities form a slag which floats on the surface and is easily removed One of the reactions to remove iron impurities is shown below

Smelting Explanation Process Impact and FAQs VEDANTU

The process usually takes place in three steps which are roasting reduction and fluxes Roasting Roasting is a process followed in the case of sulfides and carbonates that removes the unwanted carbon or sulphur and leaves behind an oxide that can directly be reduced Roasting is usually carried out in an oxidising environment

Copper extraction Wikipedia

Copper sulfide and iron oxide can mix but when sufficient silica is added a separate slag layer is formed Adding silica also reduces the melting point or more properly the liquidus temperature of the slag meaning that the smelting process can be operated at a lower temperature The slag forming reaction is FeO SiO 2 → 2
