How to Process Low-Grade Lead Zinc Ore by Flotation

Apr 27, 2016  Flotation of Lead Ore. The flowsheet above was designed to treat economically approximately 200 tons in 24 hours of a low-grade dump ore containing lead and zinc values as well as some silver in both sulphide and oxide form. Due to varying specific gravities of the values, gravity concentration in addition to flotation was indicated.
