  • Recycling of Metals | MATSE 81: Materials In Today's World

    Copper is also recycled. Once again this is a more energy efficient process than the extraction from its ore as well the copper ore supply on earth is being depleted at a very fast rate. As a result other methods for the extraction of copper such as phytomining and bioleaching are being used instead. Silver and gold from jewelry are also recycled.

    Bioleaching of nonsulfidic ores such as pitchblende also uses ferric iron as an oxidant (, UO 2 + 2 Fe 3+ ==> UO 2 2+ + 2 Fe 2+).
