The recovery and grade of unwanted lead and zinc was very low when compared to the other flowsheets. Lead in the feed was, on average, 36% recovered into a concentrate, grading 55%. Similar to the copper circuit, the grade and recovery of copper and zinc to the lead concentrate was very low.
The effect of thiourea and flotation reagents on the electrowinning of zinc from industrial electrolytes was studied, and all the compounds were found to reduce the zinc deposition current ...

Flowsheets involving zinc SX fo r the primary processing of zinc sulphides have been the subject of investigation for some time. ... Sulphide Ores and Concentrates Most zinc ores occur as sulphides and, as such, are amenable to upgrading by flotation. The traditional treatment route includes smelting of the concentrates, followed by ...

Some plants find it beneficial to use a visual sampler on the lead tailing ahead of the zinc circuit. The Sampler is also useful for evaluating the lead or zinc concentrate. General view of the flotation section at a modern silver-lead-zinc mill. The lead circuit is on the left and the zinc circuit is on the right.
1. Introduction. In practice, the commonly used method for the recovery of oxidized lead and zinc minerals from ores at present is flotation (Caproni et al., 1979; Ciccu et al., 1979; Önal and Abramov, 2002; Pereira and Peres, 2004; Dashti et al., 2004).The degree of oxidation in lead ores may range from slight tarnishing of the galena to complete oxidation.
Kinetic curves of the zinc circuit. kinetics of each mineral species; parameters such as size distribution and particle liberation (size by size if necessary) could be included in the model; the curves presented in Fig. 5 show the importance of the difference in kinetic behaviour for locked and for free particles in mechanical cell flotation of ...

The zinc reporting to the bulk flotation tails feeds the zinc circuit which is operated as previously described in the leadzinc flotation section. Which flotation scheme used in the differential copperlead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate.

With the exhausting of lead–zinc sulphide ores, the recovery of lead-zinc oxide ores becomes more and more significant. Extensive work has been carried out at home and abroad on the treatment of lead and zinc oxide ores in reagent scheme, flotation flowsheets, and joint process. Sliming is one of the main reasons why the lead-zinc oxides are difficult to recover.
River Mines routinely produce average zinc concentrate less than 10um in size, (Pease 2004). Alternatively, different flotation equipment can be added to the flowsheet such as the Jameson Cell which is well documented in the literature and proven in the field for improved fine particle flotation compared to a mechanical cell (Young 2006).
In order to illustrate the generic factors involved both in evaluating flotation flowsheets and designing the flotation circuits the development of two sulfide flotation projects, Hellyer and Cadia Mines, is compared and contrasted in the Case Studies provided later in the paper.

However, the flotation performance is difficult to be improved although many reagents and flotation flowsheets have been tested. In this study, some factors that may influence the flotation performance of this ore were tested. The objective of this study is to point out a solution to the flotation problem of low grade lead–zinc sulfide ore. 2.
To increase zinc recovery in the concentrate, this investigation performed mineralogical characterization, dispersion studies, bench and pilot-scale flotation experiments and an industrial flotation trial. The objective was to verify the flotation behavior of the silicate zinc ore (calamine type) in the presence of slimes, with the aid of dispersing agents.
The flotation concentrate is separated on tables into a zinc concentrate carrying 48 per cent, zinc, 6 per cent, lead, 4 per cent. iron, 25 oz. silver and 3 1/2 per cent, silica; and a lead-iron concentrate carrying 42 per cent. lead, 7 per cent. zinc, 16 per cent, iron, 35 oz. silver and 1 1/2 per cent, silica.
