The method used to extract metals from the ore in which they are found depends on their reactivity. For example, reactive metals such as aluminium are extracted by electrolysis, while a less-reactive metal such as iron may be extracted by reduction with carbon or carbon monoxide.
Such sources are called Ores. Extraction of metals. The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth’s 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. Ores consist of the desired metal compound and the impurities and earthly substances called Gangue.
Metal extraction from ores occurs in many different ways involving physical, chemical and electrical means. Even ores of the same metal sometimes require different methods of separation depending on...
Most of the metals occur in nature in oxidized form as their compounds. Therefore, metals are generally extracted by subjecting their ores to reduction by chemical methods or by electrolytic methods. The process of extracting pure metal from its ore is known as metallurgy. .

1. Introduction to the extraction of metals. What methods can be used in extracting metals from mineral ores? The Earth's crust contains many different rocks.. Rocks are a mixture of minerals and from some we can make useful substances.
Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is.
There are three basic ways of treating metallic ores in order to extract their metal content. Pyrometallurgy is the treatment of metals and their ores by heat. Pyrometallurgy includes Roasting, which is the heating of ores in air or heating it with a reducing agent such as carbon (coke) or carbon monoxide.
Extracting and using metals - Eduqas. Iron and aluminium are extracted from their ores in different ways because the metals have different reactivities.
Name the chief ores of copper, zinc and lead Describe and explain the general methods used in the extraction of copper, zinc and lead from their ores.

Pyrometallurgy includes Roasting, which is the heating of ores in air or heating it with a reducing agent such as carbon (coke) or carbon monoxide.
The three method generally used to extract metals from ores are dependent on their reactivity. The first method is electrolysis, which is used for metals like aluminum and magnesium that have a high reactivity. The second is extraction by reaction with either carbon or carbon monoxide, which is used for less reactive metals like iron, lead and zinc.
Metals are produced when metal oxides are reduced (have their oxygen removed). The reduction method depends on the reactivity of the metal. For example, aluminium and other reactive metals are extracted by electrolysis, while iron and other less reactive metals may be extracted by reaction with carbon or carbon monoxide. Reactivity and extraction method The method of extraction of a metal from its ore depends on the metal's position in the reactivity series.
