Flowsheet development for selective Cu-Pb-Zn recovery at Rosh …

For the high-Cu ore, the challenge was to produce three distinct Cu, Pb, and Zn concentrates. Whilst the initial approach of exploiting relative flotation kinetics using the current RPZC operating conditions did not achieve the desired Cu-Pb selectivity, a feasible flowsheet was developed based on a modified Black Mountain (Cu-Pb-Zn concentrator) processing route for …
