Abstract:
    The invention relates to a method to extract copper from abandoned breadboards and to use remain substance comprehensively recycling by combining techniques of microbe, metallurgy and materials. Based on principles of microbial wet-process metallurgy, Cu is extracted from abandoned breadboards by using iron protoxide thiobacillus. At the same time, the retained solid is recycled to realize the comprehensive treatment of abandoned breadboards. The entire recycled treatment of abandoned breadboards is realized, which guarantees the entirely clean produce without discharging waste water, waster residue and waste gas into the environment. This method has much strongpoint including little investment, low cost, high recovery rate of metal, non-pollution and green zoology etc. It benefits the society, economy and environment.
