froth flotation lead zinc

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. Rahil Khan

    If lead, zinc and copper are sulphides, the logical process is to produce a Pb-Cu bulk concentrate, and tails from the Pb-Cu flotation circuit feed the zinc flotation circuit. In this case, the lead content is much higher than copper content, then it would be necessary to depress lead and float copper
