Solid copper turns into copper two plus ions So we have solid copper turning into Cu two plus And so were losing two electrons in order to do that So solid copper turns into copper two plus we lose two electrons Loss of electrons is oxidation So oxidation occurs at our copper electrode this time and that makes this the anodeRead More
The copperbearing aqueous phase is advanced to the electrowinning EW stage of the process while the barren organic phase is returned to the extraction stage of the process In the electrowinning stage of the process the copper is reduced electrochemically from copper sulfate in solution to a metallic copper cathodeRead More
In this GCSE Chemistry quiz one of a series on metals we look at the extraction of metals such as copper from both high grade and low grade ores The knowledge of how to extract metals from their ores has played an incredibly important role in every known civilisation The ability to make coins tools and weapons from metals has changed theRead More
