Heavy metals bioremediation of soil - PubMed

As the bacterium tends to float quite easily, the biomass is separated from the water via a flocculation process. The Cd concentration in sandy soils could be reduced from 21 mg Cd/kg to 3.3 mg Cd/kg. At the same time, Zn was reduced from 1070 mg Zn/kg to 172 mg Zn/kg. The lead concentration went down from 459 mg Pb/kg to 74 mg Pb/kg.

Flowsheet development for selective Cu-Pb-Zn recovery at ...

This would enable the Pb circuit to produce a grade of 65% Pb at 81% recovery, and the Zn circuit, a grade of 57% Zn at 97% recovery. Mineralogical analysis of the final Pb and Zn products confirmed the need for the re-grinds. For the high-Cu ore, the challenge was to produce three distinct Cu, Pb, and Zn concentrates.

Lead Zinc Separation by Flotation - Froth Flotation ...

It is easier (proven) to selectively float galena by depressing sphalerite than the other way around if you are trying to make two concentrates. Bulk (or combined Pb/Zn) concentrate is the quickest way into bankruptcy because of heavy penalties imposed by smelters which becomes a real issue if your concentrate happens to contain Gold and Silver.
