Selective chalcopyrite suppression by environmentally friendly ferric chloride depressant following collector pre-adsorption in galena flotation

Key Points

• Selective suppression of chalcopyrite enhances the flotation of galena.
• Identifying an effective depressant, ferric chloride, improves mineral separation performance.
• Interventions involved pre-adsorption followed by flotation testing in various conditions.
• Environmental considerations emphasize the need for sustainable mining practices.
