Reduction of Metals (Extraction from Ore) - A-Level Chemistry

Extraction Using CarbonElectrolysisReduction of Metal Halides with MetalsMetals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is therefore reduced. The carbon gains oxygen, and is therefore oxidised.
