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 …

The Cu–Pb–As–Zn mineralization of Cap Garonne (Le Pradet, Provence, France; Fig. 1) is located in Triassic siliciclastic rocks, a few meters above the contact between Paleozoic and Mesozoic rocks (Fig. 2). It is the only known Cu–Pb–As–Zn association of Provence and surrounding areas, covering only a few hectares.

The deposits at Broken Hill, Black Mountain and the Aggeneys Mountains, contain more than 260 million tonnes of ore at a grade of 3.4% (a combination of Cu+Pb+Zn), while a concentration of 20ppm Ag is present in these ores (Ryan et al., 1982). At Gamsberg the 150 million tonnes of ore has a grade of 7.1% Zn and 0.55% Pb (scott and Taylor 1987).
