Lab-scale experiments results show that the new process contributed to the flotation of the complex mixed sulfide-oxide lead and zinc ore regarding two aspects: …
Water scarcity in the flotation plant area imposes to think of reducing fresh water use by recycling the tailing water process. Substitution of PAX by Aerophine 3418A in the zinc circuit will result in a tailing water process containing one kind of collector which could be easily controlled and recycled in the overall MCG plant.
Owing to the similarities in the physicochemical and surface chemistry of the constituent minerals, separation of zinc oxide minerals from their gangues by flotation is …
