The flotation of smithsonite from tailing which comes from the cerussite flotation circuit was investigated using Armac C and Armac T as amine collectors. The results indicated that the dosage of sodium sulfide, collector type, and desliming are the main affecting factors on the Zn grade and recovery of smithsonite flotation concentrate.

1. Introduction. The flotation of oxidized Pb and Zn minerals, particularly Zn minerals, is much more difficult than the flotation of corresponding sulfide minerals (Hosseini and Forssberg, 2007).The most common flotation technique used commercially for the treatment of ZnO minerals is sulfidization with Na 2 S, followed by treatment with conventional cationic collectors, namely amine …

chain) is used as the cationic collector for flotation of different minerals and was obtained from Akzo Nobel Co. with commercial name "Armac T" [20]. In the case of flotation of hemimorphite and willemite, it has been reported that the percentage of zinc recovery was maximized at pH=10 by using stearyl amine as a collector [13 and 21].
The pre-treatment of zinc oxide bearing ores with high slime content is important to ensure that resources are utilized optimally. This paper reports an improved process using hydrocyclone de-sliming, dispersion reagents, and magnetic removal of iron minerals for the pre-treatment of zinc oxide ore with a high slime and iron content, and the benefits compared to traditional technologies are shown.

Thus it is observed that the cationic deri-vative of guar gum is a very satisfactory gangue depressor for the froth flotation of sulphide ores. Flotation test was also carried out on artificial zinc cocentrate as feed having 193.7 gm ZnS, 6.3 gm PbS, 31.2 gm FeS 2, 0.25 gm CuS,

The increase of both collectors dosage increases Zn recovery and decreases Zn grade in the smithsonite flotation concentrate. The reduction of Zn grade is at-tributed to the flotation of more gangue minerals due to high collector concentration.

An experimental investigation is presented of the batch competitive flotation of zinc(II) and silver(I) ions from dilute aqueous solutions with sodium dodecylsulfate and ammonium tetradecylsulfonate as anionic surfactants and with cetylpyridinium chloride as a cationic surfactant.
In the flotation of Angooran zinc oxide ores (Zanjan, Iran) by oleate collector, relatively high levels of SiO 2 often report to the concentrate, which reduces the grade of Zn recovered. Quartz is considered as a dominant SiO 2 mineral as it generally constitutes the majority of gangue mineral present in the given zinc oxide ore.
Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation. The minerals that do not float into the froth are called the flotation tailings or flotation tails. The froth flotation process was first patented by …
the present study, the flotation behavior of oxidized zinc ore from Angooran deposit, Iran was studied using several cationic, anionic and mixed (cationic/anionic) collectors by means of bench scale flotation studies. 2. Materials and Methods The oxidized zinc ore samples were obtained from Angooran deposit, Iran.
A lead-zinc carbonate ore sample containing 2.5% Pb and 9.39% Zn was used in this research work. The sample was prepared from the Darreh-Zanjir mine located in the Yazd province (Iran). Influences of the influential factors on flotation of smithsonite and cerussite were investigated. Among the different parameters involved, dosages of the dispersant, depressants, sulfidizing agent, and ...
