aerofroth a frother for copper lead zinc ores flotation

Some of the metals that can do the job are copper and lead At a pH between 89 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
