| Abstract: | Acid mine drainage (AMD) was used to leach low grade secondary copper sulfide of Zijin Mountain in bio-heap leaching process. Effects of temperature, leaching method, pH value, and daily spray time on leaching rate of copper and iron were investigated applying raffinate and acid mine drainage, respectively. The results show that production index of copper bio-heap leaching with acid mine drainage is steady. Copper is recovered by 2 241.9 tons from acid mine drainage in 2014. |
