    The Birth of MetallurgyOxidation-Reduction ReactionLead from Lead OxideIron from Iron OxideMetal Activity SeriesThe ability to refine metal from metal ores is one of the most important technologies invented by civilization. The phases of human progress are marked by names like the Copper Age, Bronze Age, and Iron Age. Beyond the precious metals like silver and gold, which you can find as nearly pure metals, the only source of other pure metals came from meteorites. As you can imagine, meteorites were not a reliable source of materials to early people. On Earth, metals are often found as metal oxides. One of th

    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.

    Extraction of MetalsConvert Ores to OxidesReduction of Metal OxidesSolved Question For YouNow we already saw how the ore of a metal is concentrated to remove impurities known as gangue. After concentration of ores, we must now extract metal from in it. This step will give us metal in its pure form i.e. the native form of metal. First, we must convert the ore to a suitable form. The metals need to be in an oxide form for the reduction process to be easier. Hence the ores are converted to oxides, so it is ideal for reduction. After doing so the ores will undergo reduction, to give us metal. Therefore the two main step

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

    In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. It is possible to avoid this problem by first converting the ore to the chloride, and then reducing the chloride with a more reactive metal such as magnesium or sodium. This is the method used to extract titanium.

  • why it is easier to obtain a metal from its oxide as

    It is easier to obtain a metal from its oxide as compared to its sulphide and carbonate because when we extract metal from its respective ore, we have to perform calcination or roasting step in which carbonates and sulphides of metals are converted into metal oxides. hence in the case of oxides, we can skip this step and directly reduced oxides to obtain the metal.
