| Zusammenfassung: | The present invention provides a method of pretreating gold ore for hydrometallurgically recovering gold from gold ore containing pyrite that enables to enhance the gold-leaching speed while the generation of sulfur dioxide is suppressed. The method of pretreating gold ore comprises a step of converting 60% or more of pyrite contained in the gold ore to pyrrhotite represented by a following formula: Fei-.S (where x=0-0.2). |
