  Lead Zinc Separation by Flotation

  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. Rahil Khan
