By using purified Thiobacillus ferrooxidans was obtained from the activated sludge,leaching experiments were conducted on the printed circuit board copper.At the temperature of 30℃,pH 2,speed is 120r/min,the sample quantity,changes in particle size were investigated.The results show that,the smaller the particle size,leaching of copper ion concentration,sample volume optimal 18g/L.This shows that,the leaching efficiency in waste printed circuit board copper,sample treatment has a certain influence factors.
From activated sludge of purification are ferrous oxide Thiobacillus ferrooxidans,leaching experiment of discarded printed circuit boards using copper.At a temperature of 30 ° c,pH 2,at speeds of under 120r/min,amount of samples,changes in the particle size of leaching studies.Results showed that the smaller the particle size,greater leaching of copper ion concentration,sample the best release for 18g/L.This suggests that leaching efficiency of discarded printed circuit boards using copper,sample has a certain influence factors.

The Thiobacillus ferrooxidans obtained from the activated sludge purification,conduct on waste printed circuit board copper leaching experiments.At a temperature of 30 ° C,pH 2.0,speed under 120r/min,the amount of sample,the changes in the particle size of the leaching studies.The results showed that the smaller the particle size,the greater the leaching of copper ion concentration,the best Market sample amount of 18 g / L.This suggests that the leaching efficiency of copper in the waste printed circuit board,the processing of the sample has a certain influence factors.
