    The Extraction of Copper - Chemistry LibreTexts

    Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of ...

    Extraction of Metals Class 10 Notes EduRev

    Therefore before extracting metals form their respective ores, the metal sulphides and carbonates must be converted into metal oxides. For instance, sulphide and carbonate ores of zinc are heated to convert into their oxides. This conversion of sulphide ores into their oxides by heating strongly in the presence of excess air is known as roasting.
