IGCSE Extraction and Uses of Metals - ores
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 amounts of energy, so an expensive process. Therefore usually only used for metals more ...

Notes OCCURRENCE AND EXTRACTION OF METALS
Metals occur in nature in free as well as combined form. Metals having low reactivity show little affinity for air, moisture, carbon dioxide or other non-metals present in nature. Such metals may remain in elemental or native (free) state in nature. Such metals are called "noble metals" as they show the least chemical reactivity.

Metals with an intermediate reactivity, such as iron and zinc, are chemically extracted from minerals by a process known as carbon reduction. Carbon reduction is a type of redox reaction, where carbon is used to displace a metal from a compound. The crushed ore is mixed with carbon and limestone, then heated to a molten state (smelted) in a ...

A metal can be reduced by carbon if it is less reactive than carbon and so appears below carbon in the reactivity series. Using the reactivity series, can you name a metal that cannot be extracted from its ore using carbon? If a metal is more reactive than carbon, other chemical reactions and processes must be used in its extraction. Certain ...
