Extraction of Moderately and Less Reactive Metals
The reduction of oxides with carbon is also used to recover tin and lead metals. Copper, which is a less reactive metal, is extracted by reducing its oxide with carbon. Reduction of Metal Oxide with Aluminium-In the extraction of metals from their oxides, a more reactive metal like aluminium can be utilised as a reducing agent. When the metal oxide is of a more reactive metal than zinc, for instance, and cannot be reduced effectively by carbon, aluminium is utilised as a reducing …

How are metals with different reactivities extracted? – BBC
If a metal is less reactive than carbon, it can be extracted from its oxide by heating with carbon. The carbon displaces the metal from the compound, and removes the oxygen from the oxide….

How are the less reactive metals extracted? – Wise-Answer
How are the less reactive metals extracted? The less reactive metals are extracted by the reduction of their oxides by heat alone. Example: Mercury (II) sulphide ore is roasted in air when mercury (II) oxide is formed. When this mercury (II) oxide is heated to about 300oC, it decomposes to form mercury metal.

How Are the Less Reactive Metals (Which Are Quite Low in the Reactivity …
The ores of less reactive metals like copper and mercury are placed at the bottom of the reactivity series. Metals are extracted from these ores by heating them alone. We should note that ores of copper can be extracted by reduction with carbon (copper (I) oxide) as well as heating alone (copper (I) sulphide).

Extracting Metals in the Middle of the Reactivity Series The metals in the middle of the activity series such as iron, zinc, lead, copper, etc., are moderately reactive. These are usually present as sulfides or carbonates in nature. It is easier to do extraction of metals or obtain metal from its oxide, as compared to its sulfides and carbonates.

How are highly reactive metals extracted? – Quora
Highly reactive metals are extracted by electrolysis process. In this case,at first, the ore of the regarded metal is melt under optimum conditions. Then the molten ore is electrolysed . The metal ion is attracted by cathode and gains electron to form free metal. The extraction of metal from ore is a reduction process. As for example, Na is extracted from its ore NaCl. The reduction reaction is as follows : Na+ + 1 e = Na
