Consultant For Copper Extraction By Electrolysis Method

Methods of extracting metals There are two main methods of extracting metals from their ores: reduction with carbon electrolysis (using electricity). The method of extraction which is most appropriate depends on the reactivity of the metal being extracted. Most metals are found combined with other elements, as compounds in ores.
