Fig. 2 shows the flowchart of a zinc flotation circuit in a lead–zinc flotation plant. The first rougher is the beginning of the zinc flotation circuit, and its feed comes from the slurry of the lead flotation circuit. After the flotation of the first rougher, its froth flows to cleaner I, II, and III to obtain the zinc concentrate.
The former lead–zinc otation plant from the Boqueira mine was fed with ore from a deposit without large heterogeneity. The tailing dam of this former plant was sampled at several points (samples of about 2–5 kg), and the resulting samples were homogenized and a composite sample was used in the tests presented in this work.
Part of large-scale industrial test results of milling fineness influence on lead, copper and zinc minerals flotation results in the Rudnik flotation plant are shown in this paper. Based on industrial research it has been concluded that one-stage milling and two-stage classification of complex Pb-Zn-Cu ore leads to so-called "differential milling". Namely, galena …
With this process, copper was recovered first with MBS depression of lead, zinc and pyrite. Lead was recovered after conditioning, utilizing cyanide as the base depression scheme to control sphalerite and pyrite. In these tests, a zinc flotation was also performed to measure the metallurgical performance of that metal.
The process of the lead and zinc flotation concentration is carried out in the base environment and the cyanide is not separated in the gaseous form. However, it precipitates in tailing dumps where it is ... The objective of the industrial testing was to …
The flotation of zinc oxide minerals is suggested for sulfidization of the smithsonite followed by activation with CuSO 4 and flotation of the activated zinc oxide using xanthate at pH 10.5 [13]. It is also implied that after pretreatment of the pulp with sulfidizer followed by reconditioning with CuSO 4, zinc oxide flotation can be achieved ...
In this study, a new flotation approach, a low-alkaline and non-desliming process, was introduced for improving lead and zinc recoveries, lowering production cost and reducing …
Figure 11: Zinc depressant and Activator Dosage Versus Time Figure 12: MIBC Dosage Versus Time. Note in Figure 11 above, how the zinc activator dosage reduced over a period of time whilst zinc depressant dosage . increased. Referring to Figure 12 below, the MIBC . dosage remained relatively static post 1997. PLANT AUDIT - SEPTEMBER 2002
The separation of copper-bearing from zinc sulphides is effected by two-stage selective flotation, the zinc minerals being depressed and the copper minerals brought up in the first stage with reagents similar to those required in the lead flotation section of a lead-zinc plant; the zinc sulphides are floated in the second stage in the ordinary ...
Separating oxidized zinc minerals from flotation tailings is always a challenge. In this study, a flotation tailing from Wulagen zinc mine in China (Zn grade < 1%) was processed using froth flotation with combinations of amines (OPA 10, OPA 1214, OPA 13, DDA) and Na 2 S to study the effects of these amines on the zinc recovery as well as their interactions with other …

The conventional view of the flotation size-recovery curve is shown in Figure 1. There is a good reason for this view – if you sample almost any flotation plant you will produce a similar curve. The numbers speak for themselves – fine particles float poorly in most plants. Operators carefully avoid "overgrinding" and "sliming" of feed.
Lead-zinc ore usually exists in the form of sulfide ores, such as sphalerite and galena. Flotation is the most commonly used method.. The lead-zinc ore processing solution is adjusted and used in combination according to ore characteristics, metal grade and other factors, such as gravity-flotation, magnetic-flotation, and gravity-magnetic-flotation, in order to achieve the best …

Thus, in a lead-zinc ore, silver is more valuable in the lead than in the zinc concentrate. Similarly, in a copper or lead ore carrying gold associated with pyrite, it might be profitable to make an iron concentrate containing the gold. ... it seems likely that in the future these methods will be replaced by flotation. A flotation plant will ...
After lead flotation at optimum pH 8, the flotation of zinc at a different pH (5–11.5), with two collector types, was performed to study the recovery and grade of zinc in the zinc concentrate.

Millions of tons of zinc plant leach residues (ZPLR) have been stockpiled in Iranian hydrometallurgical zinc plants during the last few decades. Due to the low grades of zinc, lead, and silver in these residues, these residues have been abandoned without treatment. The authors of this paper studied zinc plant leach residues (ZPLR) to propose a flotation process for …
