US3969106A - Selective hydrometallurgical separation of ...

A quantitative hydrometallurgical process for the selective conversion of lead sulfide (galena) to its sulfate form under ambient conditions of temperature and pressure. The process works in the presence of associated zinc - copper - iron sulfides which survive the process in a relatively unaltered condition. It is directly applicable to ores or derived concentrates of complex sulfide systems.
