摘要
PURPOSE: A method of a bacterial leaching of chalcopyrite using a silver catalyst is provided to improve a copper leaching rate by increasing a reaction speed of a bio-leaching process of chalcopyrite. CONSTITUTION: A method of a bacterial leaching of chalcopyrite comprises the following steps: adding chalcopyrite into a medium; controlling the pH of the medium; adding a silver anion into the medium; and injecting a microorganism into the medium for leaching. The silver anion is added into the medium for 0.04~0.64g per 1kg of chalcopyrite. The medium for this method is an inorganic medium including iron sulfate.
