IGCSE Extraction and Uses of Metals - ores

ores into metals depend on how reactive the metal is. Two methods commonly used are: 1) REDUCTION WITH CARBON Used for oxides of metals less reactive than carbon – the carbon displaces the metal, stealing the oxygen to form carbon dioxide and leaving the metal. Carbon is used because it is cheap and plentiful. 2) ELECTROLYSIS Can be used for any ore, but uses huge
