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.
flotation scheme adopted for concentration of the lead-zinc ore sample consisted of differential flotation separation by depression of zinc bearing minerals using a combination of sodium cyanide and zinc sulphate as depressant and flotation of lead minerals using potassium ethyl xanthate as collector and methyl iso-butyl carbinol (MIBC) as frother.
The bulk concentrate is subsequently conditioned with sodium hydroxide to achieve an approximate 11.5 pH and collector addition from which a lead concentrate is floated. The zinc concentrate is actually the tails from this bulk separation step. The flotation tailing is the zinc concentrate.
For Copper and Lead flotation: We need to float both minerals 1st. We call it Bulk flotation. Then this bulk concentrate will go to Cleaning stage where we depress Copper, and float Lead-This process we call selective flotation. Case study-2. For Zinc and Lead Flotation. Here we depress Zinc and float Lead-This is called selective flotation
Apr 23, 2016 The problem of treating oxidized lead-zinc ores for the production of high-grade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals.

Jul 12, 2021 Flotation process and equipment of lead-zinc ore In the beneficiation of lead-zinc ore, flotation is an important process. Mixing in mixing tank: After the ground pulp is classified by the classifier, it enters the mixing tank for mixing. Control the slurry concentration at 25-35%, then add flotation agent to control the slurry pH value 9-11 and stir it for 6-15 min.

Gold recovery from copper-zinc ores is usually higher than that obtained from either a lead-zinc or copper lead-zinc ore.This is attributed to two main factors: when selecting a reagent scheme for treatment of Cu-Zn ores, there are more choices than for the other ore types, which can lead to the selection of a reagent scheme more favourable for gold flotation.
