For this purpose 0.5 kg -1.68 mm sample, crushed in stages in jaw and roll crushers, was wet ground in laboratory rod mill at 66% pulp density and floated, after ... flotation of lead and zinc bearing minerals. For flotation of zinc the xanthate dosage was varied from 0.094 kg/t to 0.752 kg/t. The results are shown in Fig. 6 ...

view more5 · Some of the metals that can do the job are copper and lead. At a pH between 8-9 lead can activate sphalerite to cause it flotation. So the reason is during the flotation of the two there may be lead re dissolution from galena which may activate sphalerite to cause it flotation. It may best if you are doing bulk flotation of the two.
