Bioleaching of copper from wasted printed circuit board by indigenous sulfur-oxidizing bacteria

Wu Sifen,Li Dengxin,Jiang Peihua.(College of Environmental Science and Engineering,Donghua University,Shanghai 201620)  
Thiobacillus thiooxidans isolated from sewage sludge was acclimated with the elemental sulfur as substrate and then employed for leaching of copper from pulverized printed circuit board(PCB)particles(75 mesh,Cu of 94.78%).100 mL of the acidic effluent(pH=1.5~2.0)from acidifying reactor was fed to the leaching reactors which respectively contained 15 g pulverized PCB particles.The initial leaching was respectively completed after 1,2,4,6 and 8 d.Subsequently,100 mL of fresh acidic effluent was respectively employed for leaching copper from solid residue in the leaching reactors after the solid-liquid separation.This operation was repeated successively for 24 d.The effect of different leaching times on the leaching efficiency was evaluated.After a contacting period of 24 d,the leaching of 24 times was able to mobilize total copper by 93.69%,12 times by 91.18%,and 6,4,3 times were by less than 70%.Because the leaching of 12 times was able to leach 91.18% of the available copper after a contacting period of 24 d with the less amount of effluent produced than 24 times,taking into account the costs of microbe cultivation and subsequent treatment,the leaching of 12 times was more appropriate than 24 times.
