Reactive metals are extracted from their ores using electrolysis. Ionic compounds conduct electricity when molten or in solution. Metal ions and non-metal ions are attracted to opposite electrodes.
It stays as a metal and falls to the bottom of the cell as an "anode sludge" together with any unreactive material left over from the ore. The anode sludge will contain valuable metals such as silver and gold. Metals above copper in the electrochemical series (like zinc) will form ions at the anode and go into solution.
Some metals are too reactive to be reduced by carbon ; For these metals they are extracted using electrolysis, e.g. aluminium from aluminium oxide (bauxite) ; To extract aluminium: Bauxite is first purified to produce aluminium oxide Al 2 O 3; Aluminium oxide is then dissolved in molten cryolite.This is because aluminium oxide has a melting point of …

This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis. Details for the extraction of aluminium, copper, iron and titanium are given in separate pages in this section. From ore ...
Extraction of metals . Many of our useful metals come from metal ores. A metal ore is a rock that contains enough of the metal to make it worthwhile extracting the metal. ... Those metals placed higher up on the series (above carbon) have to be extracted using electrolysis. Metals lower down on the series can be extracted by heating with carbon ...
Lower placed metals can be extracted by heating with carbon which reduces. Electrolysis is very expensive as large amounts of energy are required to melt the ores and produce the electrical current. The reactivity series of metals is shown below with the corresponding …
The position of the metal on the reactivity series influences the method of extraction; Those metals placed higher up on the series (above carbon) have to be extracted using electrolysis; Metals lower down on the series can be extracted by heating with carbon; The Extraction Method Depends on the Position of a Metal in the Reactivity Series

Choosing methods for metal extraction. The position of the metal on the reactivity series determines the method of extraction; Higher placed metals (above carbon) have to be extracted using electrolysis as they are too reactive and cannot be reduced by carbon Lower placed metals can be extracted by heating with carbon which reduces; …
The least reactive metals are found in their native state in the Earth's crust.This means they are found as uncombined elements. Any metal more reactive than hydrogen, but less reactive than carbon, can be extracted by adding carbon to displace the metal from its oxide (or other compounds).This is known as reduction.. The most reactive metals have …
Carbon extraction. Any metals which are lower than carbon in the reactivity series can be extracted using reduction where carbon is used as the reducing agent. Although other methods such as electrolysis could also be used for these metals, reduction using carbon is the cheapest method.
