Lead zinc 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

    Apr 20, 2016 The process consists of selective flotation to produce a mixed silver-lead concentrate for maximum smelter return and a separate zinc concentrate. Over-grinding of silver minerals is detrimental to efficient flotation recovery, so the Flash Flotation Unit-Cell is used in the grinding circuit to recover a large part of the silver and lead values as soon as liberated

    Apr 23, 2016 Lead Zinc Flotation Several processes have been developed for the separation of lead from zinc sulphides by two-stage selective flotation , but the only method that is employed widely enough to warrant a description in these pages is the one whereby the zinc minerals are depressed by sodium cyanide and/or zinc sulphate, allowing the galena, which remains unaffected, to be floated in the first

    Application of cyanide in Lead-Zinc (Pb/Zn) flotation dates back from 1922 when Sheridan-Grisvold process was introduced using the cyanide as depressant for the sphalerite and pyrite. The cyanide was proven to be a very efficient depressant and it is still used extensively in flotation. There is a patent on

    At a pH between 8-9 lead can activate sphalerite to cause it flotation. So the reason is during the flotation of the two there may be lead re dissolution from galena which may activate sphalerite to cause it flotation. It may best if you are doing bulk flotation of the two. Rahil Khan
