  • Effect of activated carbon on growth of bacteria and leaching of copper was investigated. The results showed the addition of activated carbon could inhibit the growth of bacteria. And the inhibition was weakened with higher addition. The copper was leached rapidly with ferric ion. The addition of activated carbon could promote leaching at a certain extent, but the effect was not obvious. And the leaching rate was 87% finally. The addition of activated carbon promoted the leaching of copper for increasing the biomass in system of leaching, enhancing oxidation of ferrous ion and keeping higher concentration of ferric ion. To promote leaching, the activated carbon addition should be higher.

Abstract: Effect of activated carbon on growth of bacteria and leaching of copper was investigated. The results showed the addition of activated carbon could inhibit the growth of bacteria. And the inhibition was weakened with higher addition. The copper was leached rapidly with ferric ion. The addition of activated carbon could promote leaching at a certain extent, but the effect was not obvious. And the leaching rate was 87% finally. The addition of activated carbon promoted the leaching of copper for increasing the biomass in system of leaching, enhancing oxidation of ferrous ion and keeping higher concentration of ferric ion. To promote leaching, the activated carbon addition should be higher.
