| titleOfInvention | Method for strengthening biological leaching of copper blue by comprehensively utilizing ferric ions and ferrous ions |
| abstract | The invention belongs to the technical field of biological metallurgy, and particularly relates to a method for strengthening biological leaching of copper blue by comprehensively utilizing ferric ions and ferrous ions, which can be used for improving the leaching efficiency of low-grade copper sulfide ore. Specifically, ferric sulfate and sulfur oxidizing bacteria are used as a leaching agent to leach copper blue; then adding iron-oxidizing bacteria into the leaching system to realize leaching. The method realizes the efficient utilization of the iron source and bacteria, and avoids the premature generation of passivation substances such as dense jarosite on the surface of the mineral caused by the addition of exogenous iron and the limitation of a sulfur layer formed on the surface in the reaction process on the reaction rate. The invention has important significance for improving the biological leaching efficiency of the chalcocite. |
