The effect of zinc cyanide on the flotation of gold from pyritic ore
Fig. 2 shows Au, Fe and S flotation recoveries at the end of flotation as a function of NaCN concentration. Both 3418A and PAX were applied in the flotation. As can be seen, Fe and S recoveries decreased to 6.9% and 4.5%, respectively, at 4 × 10 −4 M NaCN. Further increasing NaCN concentration to 2 × 10 −3 M had little influence on the already low Fe and S …
