Obtaining and using metals

Most metals are extracted from ores found in the Earth's crust. The method used to extract a metal from its ore is linked to the reactivity of the metal. Part of the reactivity series is shown in Figure 14. Figure 14 * Aluminium is extracted from its ore by electrolysis. Iron is extracted from its ore by heating with carbon.

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.

Why is copper not extracted by electrolysis?

Why is copper not extracted by electrolysis? The extraction method used depends upon the metal's position in the reactivity series . In principle, any metal could be extracted from its compounds using electrolysis . However, large amounts of electrical energy are needed to do this, so electrolysis is expensive.

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.

Electrolytic production of copper from chalcopyrite

With a binary BaS–Cu 2 S electrolyte, cathodic electrochemical reactions were demonstrated, and for the first time, liquid copper was extracted from a molten sulfide melt. Molten sulfide electrolysis is promising not only for the single-step extraction of copper but also to selectively extract other elements contained in the ore concentrate.
