gold in copper rougher flotation tailings (0.07% Cu, 0.61g/t Au, tail grades). An aeration stage was applied both at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher tailings, before gold/pyrite selective flotation. Also, different collector

Mine production over the past few years has been from both silver-copper and silver-lead ores ...
In Tailings: The lead losses in the tailing varied from 0.12 to 0.47%. Most of the sulphide lead in the tailing was in the form of locked particles, that is, small grains of galena attached to other sulphides or gangue minerals. Finer crushing and froth flotation would enable recovery of most of this lead.
Two-stage selective flotation is used, where the zinc and iron minerals are depressed, allowing the galena to float, followed by the activation of the zinc minerals in the lead tailings to allow a ...
In this paper, based on the experiment on pure minerals, namely, galena, sphalerite and pyrite, it is concluded that the appropriate pH range for galena flotation is 8.5-10.5, that for sphalerite flotation is 7-10.5 and for pyrite is 2.5-6.5. For galena, sphalerite and pyrite, butyl xanthate has a better collecting performance than ammonium dibutyl dithiophosphate.

shown, for example, that in the tailing from a galena flotation process the lead content generally increases with decreasing size of the slime partioles and that the product "minus 200 mesh" or "minus 325 mesh" assays high est in lead. However, on account of the lack of a suitable means of separating the material into fractions oontain
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
galena flotation tailing; Study on Recovery of Lead-Zinc Tailing Ore by, In the electrochemical potential controlling flotation processing, using DDTC as collector, the separation potential range of galena and sphalerite with pyrrhotite can be achieved Flotation circuit of lead-zinc-silver tailing …
Jan 01, 2014· While in the presence of PAX (Potassium Amyl Xanthate), the grade of Pb and Zn in rougher concentrate step was 66.8% and 10%, respectively. Tailing of the galena flotation (with 8.48% Pb grade and 34.92% Zn grade under the optimal conditions) was used as a feed for sphalerite and oxide section flotation.
flotation recoveries of galena and sphalerite are discussed in Chapter 5. The flotation results indicate that high dosages of xanthate collector of long chain length such as PNBX are detrimental to the flotation selectivity between galena and sphalerite. As expected, Cu(II) is a much stronger activator for sphalerite than Pb(II) ions. It is also
A method for the extraction of both Pb and Mo from molybdenite flotation tailings associated with galena is described. The flotation tailings were pre-roasted and then alkaline leached. The effect of temperature, initial concentration of sodium hydroxide solution, alkali to total calcine mass ratio, leaching time and stirring speed on the ...
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air …
For the mixed binary mineral micro-flotation test, the mass ratio of chalcopyrite and galena was 1:1 for the flotation feed (1.0 g chalcopyrite + 1.0 g galena). The flotation operation was the same as the single mineral flotation test. After flotation, the concentrate and tailing …
utilization and recovery from gold cyanidation tailings. ZHU et al  showed that galena and sphalerite in cyanidation tailings were floated and recovered well by xanthate as a collector, where activated carbon was used to adsorb excess cyanide and residual flotation reagents in the process of gold cyanidation. LV et al  proved
The sulphidized lead minerals are subjected to flotation using xanthates or mercaptans and pine oil to produce a flotation concentrate which is cleaned two times to produce a high grade marketable lead concentrate. The flotation tailing from the lead section passes to a wet cyclone to make a primary sand-slime separation.
In each of these detailed investigations, a stage flotation technique (1) was used to float and collect several galena fractions. For each test, the results are represented by two curves – one showing the amount of xanthate with the floated fractions, and the other showing the xanthate with the tailing.
In this work, the flotation recovery of sphalerite and pyrite from an old high zinc grade tailing was studied. In particular, the effect of different flotation reagents such as collector ...

Evolution of the pulp potential and the dissolved oxygen concentration in the flotation cell during the flotation of a Rosh Pinah composite ground in either a dry or wet environment in a steel mill.
May 01, 2015· Flotation tailings dump material of the former lead–zinc mine near Freiberg (Germany) consists of fine grained quartz, feldspar, mica as well as the sulphide minerals pyrite, galena and sphalerite not recovered by flotation. Sphalerite contains, aside from iron, copper and cadmium, significant amounts of indium (up to 0.38% (w/w)) leading to ...

Tailing x - Keagents used in unmeasured quantities until required pH was obtained. In a third flotation test, a selection of 0.1 Ib per pound A final flotation test was made in which a bulk sulphide of Z-11 was made and the amount of cyanide was increased was produced, and then ground for an additional 20 to 1.0 pound per ton.
The zinc concentrate is actually the tails from this bulk separation step. The flotation tailing is the zinc concentrate. If the silver is associated with the galena, the silver reports to the lead concentrate. While pyrite is fairly easy to depress with lime, pyrrhotite is more difficult to depress.
Tailing of zinc flotation is the final tailing which is sent to the tailing yard after concentration. The water from concentration and filteration can be reused. Zinc and Lead Mineral process and concentrates by Flotation separation and recovery from ores containing galena (PbS) and sphalerite (ZnS) is well established and generally achieved ...
