  • extraction of copper from copper pyrite| grade 12 science

    extraction of copper from copper pyrite| grade 12 science

    The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process

    Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable
