To address the challenges of cyanide toxicity and environmental pollution in conventional cyanidation gold extraction, this study proposes an innovative process combining superactivation pretreatment with an environmentally friendly leaching system. The superactivation pretreatment effectively exposes encapsulated gold phases in gold-bearingroasting slag, overcoming inefficiencies  in traditional gold recovery.  An enviromentally friendly  leaching agent was employed for clean gold extraction. Under optimal conditions: 25 °C, enviromentally leaching agent dosage of 1.2 g/L, activated carbon dosage of 30 g/L, liquid-solid ratio of 4, reaction time of 3 h, air flow rate of 2.0 L/min, stirring speed of 400 r/min, and pH 11.0-11.5, gold leaching efficiency reached 96.2 %, enabling high-yield and eco-friendly extraction from gold-bearing roasting slag.
