REFRACTORY GOLD ORES: A CRITICAL REVIEW OF MINERALOGY AND PROCESSING OPTIONS
REGISTRO DOI: 10.69849/revistaft/ra10202512141446 Antonio Clareti Pereira1 Abstract Refractory and double-refractory gold ores continue to challenge conventional hydrometallurgical processing due to the combined effects of sulfide encapsulation, carbonaceous preg-robbing, and complex gangue mineralogy. This review integrates mineralogical diagnosis, pretreatment technologies, leaching systems, recovery methods, operational constraints, economic factors, and environmental considerations to provide a comprehensive framework
