Copper Refiningan overview ScienceDirect Topics
Again the process does not incur changes in the electrolyte. Copper is primarily extracted from copper sulfide first by converting sulfide to oxide (roast) followed by carbothermic reduction. However the product still contains too many impurities and needs refining which is achieved by electrolysis using impure copper as the anode.

Process Of electrolytic Refining is described below firstly the apparatus for the electrolysis consist of Electrolytic tank containing acidified copper sulphate solution as electrolyte. Then a thick block of impure copper metal is dipped as anode. A thin strip of pure copper metal is dipped as cathode. Now elcetricity is passes through the

Chat OnlineThe application of S−2→S 6 chemistry to the refining of copper
It has been demonstrated that the ancient process of chloridizing roasting functions as a reduction process for copper oxide when carried out in a closed condensed system. Thermodynamic data are tabulated to show that this reduction process is highly selective for copper thus it is potentially useful as a copper refining process. The results of brief experimental programs are reported for
Chat OnlineElectrolytic RefiningMeaning Electrorefining of Copper
Electrolytic refining is a process of refining a metal (mainly copper) by the process of electrolysis. As far as the mechanism of the process is concerned during electrolysis a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the cathode.

Chat OnlineCopper Refining Explained Step-by-Step
· In refining 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 has copper. In these operations some of the copper is oxidized to cuprous oxide and dissolved by the metal bath.
