Extraction of Metals - Methods of Extraction of Metals from Ores

Extraction of metals. The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earths crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges.

Metal extraction and the reactivity series - Iron and ...

We can see from the table that reactive metals, such as aluminium, are extracted by electrolysis, while a less reactive metal, such as iron, may be extracted by reduction with carbon.

GCSE Chemistry - Metals Page

The method used to extract a metal from its ore is linked very closely to that metal's position in the Reactivity Series. The more reactive a metal is the more it wants to form compound and therefore the harder it is to isolate the pure metal from its compounds.

Occurrence of Metals: Metal Ores, Methods of Extraction, Examples

Metals of high reactivity level. Metals in the top of the reactivity level i.e. metals like sodium, magnesium, calcium, etc cannot be obtained from their compound by heating with carbon as they are very reactive. Electrolytic reduction is used to obtain such metals. Metals of medium reactivity level

extraction of metals - introduction

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.

Extraction Of Metals | Definition, Factors & Occurence

Electrolysis is method used with these cases of metals. Metal in form of molten form is used. Class 3: Electrolysis and reduction in used for reactive metals with high valency. Class 4: Roasting and reduction methods are used for extracting heavy metals. Examples are iron, copper, nickel and cobalt. Class 5: Amalgamation and cyanide process of extraction are used for less reactive metals.

How is the method of extraction of metals high up in the ...

1 Answer. Metals high up in reactivity series are extracted by electrolytic reduction. While those in the middle are extracted first by converting into oxide and then reducing by carbon. 1 Same method cannot be used because metals have more affinity for oxygen than carbon. Molten sodium chloride is taken for electrolytic reduction.

Metals of high reactivity; such as sodium, calcium, magnesium, aluminium, etc. are extracted from their ores by electrolytic reduction. These metals cannot be reduced using carbon because carbon is less reactive than them. Electrolytic Reduction: Electric current is passed through the molten state of metal ores.

Reduction of Metals (Extraction from Ore) - A-Level Chemistry

In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. It is possible to avoid this problem by first converting the ore to the chloride, and then reducing the chloride with a more reactive metal such as magnesium or sodium. This is the method used to extract titanium.

Extracting Metals by Electrolysis - Todmorden High School

Methods of extracting metals There are two main methods of extracting metals from their ores: reduction with carbon electrolysis (using electricity). The method of extraction which is most appropriate depends on the reactivity of the metal being extracted. Most metals are found combined with other elements, as compounds in ores.
