Copper Lead Zinc Polymetallic Sulfide Flotation Circuit Circuit Overview This flotation circuit is configured for polymetallic sulphide ores in which copper, lead and zinc report together in the same orebody. Unlike a single flotation cell, the circuit is designed as a complete process route: ore is ground to liberation, conditioned with reagents, and separated through roughing, scavenging and cleaning stages into copper, lead and zinc concentrates.
