Extraction of metals from metal oxides - Amazon S3

Extraction of metals from metal oxides . The less active metals either have . minerals. that are oxides, eg iron, or the oxide can be readily obtained from the mineral (often the metal sulfide), eg zinc, lead and copper. The metal is extracted by thermal reduction of the metal oxide using carbon (in the form of

Science - Extraction of metal from metal oxides

Lead can remove the oxygen from copper oxide and silver oxide, but not from zinc oxide. This makes it easier to extract metals that are further down this list, like silver or copper - than the ones higher up in the list, like aluminium or zinc. We'll add another element to the list: carbon - a non-metal.
