by higher Cu and lower Pb grades than the 'low Cu' ore. Rough eco-nomic value calculations showed that value in the low Cu ore was contained largely in sphalerite (67% Zn) and galena (29% Pb) whereas for the high Cu ore, it was biased towards sphalerite (85%) and chal-copyrite (13%), with galena contributing only 4%. This implies that Zn

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 …
