Lead-Zinc ores - Danafloat

Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit, typically lime is used to raise pH for iron sulphide depression. The flotation collectors used in sphalerite flotation tend to be less powerful because sphalerite at this stage typically readily floats and using a more aggressive ...

ADVANCES AND APPLICATION OF LEAD ALLOY ANODES

Lead alloy anodes employed in Zn electrowinning (EW) typically contain between 0.25 to 1.0% wt Ag. These anodes are either cast or rolled and have a flat or corrugated shape. New lead alloy anodes require a relatively long time to form an adherent, protective PbO2/MnO2 layer that can evolve O2 without excessive Pb contamination of the Zn cathode.
