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.
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...
Learn about the processes that are related to extraction of metals and learn about the reactivity series with BBC Bitesize GCSE Chemistry (WJEC).
Electrolysis is used to extract reactive metals from molten ores (melted materials containing metals). Electrolysis is used to extract metals such as aluminium, which are higher in the reactivity series than carbon.
The most reactive metals will react with cold water: Products are a metal hydroxide (forming an alkaline solution) and hydrogen gas. E.g. with potassium: 2K + 2H2O -> 2KOH + H2. Fairly reactive metals react with acids: acid + metal → salt + hydrogen.

process Electrolysis of water Electrolysis can be used to separate water into hydrogen gas, H 2 (g), and oxygen gas, O 2 (g). The overall equation for this reaction is: 2H 2 O (l) → 2H 2 (g) + O 2 (g)

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.
