Web12 de nov. de 2024 · Electrolysis of molten compounds is used to extract the most reactive metals. In principle, all metals can be extracted using electrolysis but it is expensive. If a metal is less reactive than carbon, it is cheaper to extract it by heating with carbon. The very least reactive metals, such as gold, occur as pure elements, Web3b. Electrolytic extraction of the very reactive metal like sodium. The process of electrolysis uses of large amounts of energy in the extraction of a reactive metals like sodium, potassium, magnesium and calcium etc. and makes them expensive to produce.. Because its position in the reactivity series of metals, sodium cannot be extracted using carbon, …
WebCopper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper (II) sulphate solution. Concentration of the copper (II) sulphate solution by solvent extraction.
