froth flotation for leadzinc

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

    May 26, 2021 At the Huili lead-zinc dressing plant, flotation of lead-zinc sulfide ore was divided in two parallel series, each of which had the process capacity of 522 tons/day. After the flotation of sulfide lead-zinc minerals, the tailings of the two series merged together into hydro-cyclones for de-sliming, and then the underflow of the hydro-cyclones entered into the zinc oxide ore flotation circuit
