Two processes used to extract metals are pyrometallurgy, which involves high-temperature processes such as smelting, and hydrometallurgy, which involves using aqueous solutions to extract metals from ores.
Metals are less reactive than carbon, so they are commonly extracted using reduction reactions. This involves using a more reactive substance, like carbon or a metal, to remove oxygen from the metal ore, leaving behind the pure metal. The reduction process helps to separate the metal from its ore efficiently.
Aluminum is placed above carbon in the reactivity series, meaning it is more reactive than carbon. It reacts with acids to release hydrogen gas and with metal oxides to produce metals. However, it is less reactive than metals like sodium and potassium.
Start with a more reactive metal or element and a less reactive metal or element in solution or in contact with each other. The more reactive metal will displace the less reactive metal from its solution or compound, resulting in a new compound containing the more reactive metal and a separate less reactive metal. The displacement reaction follows the activity series of metals, where more reactive metals displace less reactive metals from their compounds.
Metals can be arranged in an activity series based on their reactivity. More reactive metals are placed in a solution of less reactive metals to displace them and form a metal salt solution, while less reactive metals remain unreacted.
Much more recently than the less reactive. The more reactive metals are not found free in anture but are all in chemical compounds, anf they are more difficult to extract.

Displacement reactions are used to extract metals from their compounds by replacing a less reactive metal in a compound with a more reactive metal. The more reactive metal displaces the less reactive metal from the compound, resulting in the desired metal being extracted in its elemental form. This process is commonly used in metallurgy to obtain pure metals from their ores.

Metals less reactive than carbon, such as copper and silver, are extracted by reduction using carbon as a reducing agent. The metal oxide is heated with carbon (in the form of coke) to form carbon monoxide, which then reduces the metal oxide to the pure metal and carbon dioxide.
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
Aluminum is placed above carbon in the reactivity series, meaning it is more reactive than carbon. It reacts with acids to release hydrogen gas and with metal oxides to produce metals. However, it is less reactive than metals like sodium and potassium.

The displacement reaction follows the activity series of metals, where more reactive metals displace less reactive metals from their compounds.
Non-metals do not show displacement reactions because they are less reactive than metals. Displacement reactions occur when a more reactive element displaces a less reactive element from its compound. Since non-metals are not as reactive as metals, they are not typically displaced in reactions.
Almost all the rest of the metals.
