Lead and Zinc Energy

6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

further followed by flotation of zinc minerals (Gokhale et.al., 1983). During flotation, pyrite is rejected into the tailings by adding suitable depressants like sodium sulfide and cyanides. In this process some portions of sulphide minerals of lead, zinc and precious metals like silver and cadmium are also lost into the tailings as metal losses.

Lead Zinc Separation by Flotation Froth 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.
