Recovery of zinc and lead from zinc plant residue
After liquid/solid separation, the pregnant solution is purified and electrowon for metallic zinc production. In some plants (e.g., Çinkur, Kayseri, Turkey), the zinc leach residue is stockpiled for future lead recovery. These residues are considered as hazardous wastes due to their significant zinc, lead, and cadmium content.

How to Increase Germanium Extraction from Zinc …
As seen, leaching the H2SO4-leached residue with 250 kg/mt HF for 2 h at 80°C and 10% pulp solids extracted 93 % of the remaining germanium, bringing total germanium extraction from approximately 70 to 98%. (The high cost of HF could make this alternative less viable.) Modify the two-stage zinc leaching procedure.
