Fig. 2 shows that as pH increased from 9.0 to 10.5 and then to 11.5, the pyrite recovery obtained from the flotation of the ore with 5 % pyrite decreased steadily from 94.5 to 40.6 % and then to 10.3 %. Hence, a direct link between the decreased pyrite recovery in Fig. 2 and the increased Cu grade in Fig. 1 when pH increased could be drawn. The …
