- The method used to extract a metal depends largely on its reactivity. Metals more reactive than carbon, such as aluminium and sodium, need to be extracted using electrolysis. Metals less reactive than carbon, like iron, zinc, copper, can be extracted from their ores by reduction using carbon.

Dec 11, 2019 · Ideas for the classroom. Many metals can be reduced and extracted in a school laboratory. The easiest are iron, copper and lead. Over several lessons students can be taught how a metal is extracted and reduced from its ore. As you introduce each new example, increase the complexity of the chemistry.
Metals like copper, zinc, or lead, which are moderately reactive, can be extracted from their ores by heating them with carbon or carbon monoxide. This is known as reduction with carbon. For highly reactive metals like sodium, calcium, aluminium, and potassium, extraction of metal from the ore involves electrochemical methods.
