Web7 de jun. de 2024 · 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 … WebThus, as a result, once the metal ore has been extracted from the ground, they need to be converted into its pure metal form. This process of extracting metals from their ore is known as metal extraction. The process of electrolytic reduction is used to turn the concentrated ores into metal oxide.
