How to Effectively Separate Copper and Lead from Lead-Zinc Ores?

Separating copper from lead in lead-zinc ores remains one of the toughest challenges in mineral processing. Traditional methods create environmental concerns, while new approaches promise cleaner solutions.

Effective copper-lead separation requires the selective inhibition of one metal while allowing the other to float. Traditional methods utilize toxic chemicals, such as chromates and cyanides, whereas modern approaches employ environmentally friendly reagents, including organic polymers and sulfites, to achieve similar results.

Let?s first examine the traditional methods and their drawbacks before exploring newer, more sustainable alternatives.
