Copper-Lead-Zinc ores

Generally the lead mineral, typically galena, readily floats and optimum collector selection for copper will provide good lead recoveries. In some cases, maximizing bulk copper recovery may require use of thiocarbamate and thionocarbamate collectors in conjunction with dithiophosphate and xanthate chemistries in bulk flotation.

Nowadays, biomining is commercially applied to treat refractory gold ores and marginal ores. However, the biorecovery of copper, zinc and lead from polymetallic ores and mining waste are missed. In this framework, biomining is a promising alternative, especially to recover target metals from polymetallic and low-grade ores, and from mining waste.
