metals extracted from ores by electrolysis

Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis Metals with low chemical activity such a gold and silver are normally found in their pure

The Extraction of Copper

Any metal in the impure anode which is below copper in the electrochemical series (reactivity series) does not go into solution as ions It stays as a metal and falls to the bottom of the cell as an anode sludge together with any unreactive material left over from the ore The anode sludge will contain valuable metals such as silver and gold
