extraction of mining from ore igcse tes resources

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more .

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.
