A method for the leaching of chalcopyrite by batteries Assisted bacteria

摘要

Comprising: (a) providing a Stack of Mena, Aired in or near a base thereof, containing chalcopyrite to oxidize Sulphide minerals in it,The Stack Containing and / or being inoculated with a bacterial culture that oxide Sulphide or oxide iron into FERRIC oxide,Or it is inefficient; b) providing at least a First Solution Dissolution Pond,From which the solution is brought to power the battery receiving solution and Dissolution of the Pile; and,(c) exude a portion of the solution Dissolution and into a system for the Recovery of metals.The First Pond is maintained with a low concentration of FERRIC oxide on the iron concentration, and maintained with an Oxidation Reduction Potential under 500 mV.The oxidation of chalcopyrite is achieved with quimiolitotropicas bacteria
