H2O2-mediated surface chemistry converts a non-selective depressant to galena-selective for efficient Cu–Pb flotation separation

Key Points

• Galena selectivity increases due to H2O2-mediated surface chemistry modifications, improving flotation efficiency.
• Analysis reveals a significant enhancement in selectivity, reaching up to 80% in a controlled environment.
• This study employs surface chemistry techniques to convert a non-selective depressant into a galena-selective one.
• The findings highlight the potential for better separation strategies in mineral processing, enhancing resource recovery.
