01-11-2019· An example of a sequential Cu-Pb-Zn flowsheet is given in Fig. 14. A first flotation stage is carried out at low pH (pH 6), in which the copper sulphide is floated while both galena and sphalerite are depressed. As shown in Fig. 13, at low pH both lead and zinc float poorly, while copper can still be recovered at high values.
