I think you should increase the dosage it seems low For example if the head grade reports 1 Pb and 3 Zn the addition of ZnSO4 could be 700 gt in grinding 100 gt in rougher flotation In this case activated sphalerite is not a problem NaCN should be added in the grinding circuit eg 2030 gtView Detail
