By reducing metal ions in compounds, we can extract metals for our use and literally build the world around us. What students need to know • An ore is a mineral that contains enough metal to make it worth extracting the metal. Carbon can be used to extract metals from some metal oxides. • A metal can either be reduced or oxidised in a …
Introductory Chapter: Extraction Metallurgy – New …
For example, investigating the use of bioleaching to extract copper from its ore is proving to be an efficient process by using microorganisms to break down the sulfide minerals in copper ore [15, 16]. This process might prove to be more environmentally friendly than traditional smelting as it produces fewer emissions and requires less energy.
Extracting Metals by Electrolysis
Extraction of metals by electrolysis is a method of obtaining a metal from a mineral. About Extracting Metals by Electrolysis Electrolysis is usually used to extract metals when the metal is more reactive than Carbon or the mineral is soluble in water making it cheaper to extract by electrolysis than by smelting.

4.1.6.2: The Extraction of Copper
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores.
Extraction of Metals from Ores – Different Processes Involved
The extraction process depends on the physical and chemical properties of the constituents of an ore. The extracting metals low in the activity series will differ from those which are higher in the series.
Lesson Explainer: Extracting Aluminum | Nagwa

Extraction of Metals and Reduction | GCSE Chemistry Revision
Extracting metals by heating them with carbon is more cost-effective than using electrolysis. However, if a metal is more reactive than carbon, it cannot be reduced by carbon. In this case, the metal has to be extracted using electrolysis. Unreactive metals, such as gold and silver, are found in the Earth's crust as pure metals.
Aluminium Metallurgy
Instead, it is extracted by electrolysis. The ore is first converted into pure aluminum oxide by the Bayer Process, and this is then electrolyzed in solution in molten cryolite - another aluminum compound. The aluminum oxide has too high a melting point to electrolyse on its own. The usual aluminum ore is bauxite.
