- The process of extracting a metal often involves removing the oxygen to obtain the pure metal. This is reduction, as it involves the loss of oxygen. So, metal oxides are often reduced to obtain pure metals.

Metals can be arranged in order of reactivity by observing their reactions with water, acid and displacement reactions with other metal compounds. This determines how it is extracted from its...
Different methods are used to extract a metal depending on its position in the reactivity series. The diagram shows a simple reactivity series, including carbon and hydrogen.
Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied.
Jul 12, 2023 · Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into purer form. The field of extractive metallurgy encompasses many specialty sub-disciplines, including mineral processing, hydrometallurgy, pyrometallurgy, and electrometallurgy.

The extraction process typically involves reduction, where the positively charged metal ions in an ore gain electrons. This change transforms them into their neutral, pure metallic form. For example: When a zinc ion (Zn 2+) gains two electrons (which is reduction), it forms pure zinc: Zn2+ (aq) + 2e– → Zn (s)
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.
