Electrolysis in Metal Extraction AQA GCSE Chemistry

The position of the metal on the reactivity series determines the method of extraction. Higher placed metals (above carbon) have to be extracted using electrolysis as they are too reactive and cannot be reduced by carbon.; Lower placed metals can be extracted by heating with carbon which reduces.; The process is very expensive as large amounts of energy are required to melt the ores and
