How to Process Copper Lead Zinc Ore with Gold and Silver by …

The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper (16 pounds per ton) or more.
