zinc sulfide ore flotation

zinc sulfide ore flotation

Aug 23, 2021 Sulfide-xanthate flotation method. The sulfide-xanthate method is one of the effective ways to recover lead-zinc oxide ore. The principle is to sulfide the lead-zinc oxide ore in advance. The lead-zinc oxide ore surface is covered with a sulfide film with strong hydrophobicity, and then a xanthate collector is used to activate it under the ...

  • Method of flotation of sulfide copper zinc ores

    Method of flotation of sulfide copper zinc ores

    Copper-zinc ore is enriched by the scheme of direct selective copper flotation. The ore is ground with the addition of calcium oxide to create an alkaline environment and depression of pyrite, sodium sulphide and zinc sulphate for depression zinc materials. The crushed pulp is subjected to conditioning with reagents-regulators sulfur NAT is ...

  • How to Select the Froth Flotation Method Used in the

    How to Select the Froth Flotation Method Used in the

    Feb 26, 2020 Potential-controlled flotation method used in the extraction of the lead-zinc processing is to change the electrochemical conditions of flotation system to control the process and direction of oxidation-reduction reaction on the surface of the sulfide minerals in the slurry system, thus affecting the surface state of sulfide ore, the product ...

  • Recycle of Wastewater from Lead Zinc Sulfide Ore Flo

    Recycle of Wastewater from Lead Zinc Sulfide Ore Flo

    Lead-zinc sulphide ore contains lead sulphide (galena), and zinc sulphide (sphalerite). In the first flotation stage, galena is rendered hydrophobic with an organic collector such as xanthate, while sphalerite is kept from floating by depressants, and in the second flotation stage, activator was used to activated zinc flotation.

  • Zinc Recovery from Wulagen Sulfide Flotation Plant Tail by

    Zinc Recovery from Wulagen Sulfide Flotation Plant Tail by

    The adsorption of collector onto pure smithsonite particles was investigated to justify the differences in the zinc flotation with different collectors. Pure smithsonite particles were obtained from Wulagen sulfide ore tailings by manual picking using a microscope, and the selected particles were ground to less than 2 μm with an agate mortar.

  • US10005088B2  Flotation of sphalerite from mixed base

    US10005088B2 Flotation of sphalerite from mixed base

    This warrants only changing the flotation collector in zinc flotation stage from, for example, potassium amyl xanthate (PAX) to the new collector. Flotation of sphalerite from mixed base metal sulfide ores either without or with largely reduced amount of copper sulfate addition using 2 …

  • Flotation Behavior of Complex Sulfide Ores in the Presence

    Flotation Behavior of Complex Sulfide Ores in the Presence

    Jun 12, 2017 Base metals such as copper, lead, and zinc are mainly extracted from sulfide ores. Mostly these base metals tend to exist together in an ore. Flotation process is widely used to separate these minerals in sulfide ores . A wide range of chemical reagents are used in the flotation process to separate the different minerals.

  • O Isopropyl N Ethyl Thionocarbamate Z 200  CNFREE

    O Isopropyl N Ethyl Thionocarbamate Z 200 CNFREE

    Used as the flotation collector for non-ferrous metal complex sulphide ore with medium selectivity and strong flotation ability, which is suitable for polymetalic sulphide ore consisting copper, lead zinc and so on. In the natural loop, it is particularly effective in the flotation for …

  • Brief Introduction of Dithiophosphate

    Brief Introduction of Dithiophosphate

    Apr 24, 2019 It is an effective collector for copper, lead and silver sulfide ore and activated zinc sulfide ore. It is commonly used in the priority flotation separation of lead ore and zinc ore. In the alkaline medium, the dithiophosphate 25 has weak collecting effect to pyrite and other sulfide minerals, and has certain selectivity.

  • Current Situation on Flotation of Cu Pb Zn Sulfide Ore

    Current Situation on Flotation of Cu Pb Zn Sulfide Ore

    A flotation test on a refractory lead-zinc ore [was carried out 13]. It was found that the zinc sulfide and pyrite was effectively controlled without sodium cyanide by adjusting pH of the pulp with CaO when the pH value was 12 ( about -120 mV). Under the condition of getting a similar concentrate grade, the Pb and Zn recovery was 9.08 %

  • Surface chemistry investigation of froth flotation

    Surface chemistry investigation of froth flotation

    3 rows Jan 01, 2021 In the mineral processing industry, lead-zinc sulfide ores are usually processed by froth ...

  • Preferential Flotation of a Refractory Cu Pb Zn

    Preferential Flotation of a Refractory Cu Pb Zn

    in Zinc-Sulfur Sulfides Bulk Roughing. A roughing process is adopted to the zinc and sulfur bulk flotation from lead tailings. Collector butyl xanthate dosage of 200 (g / t) and foaming agent pine oil of 15 (g / t) are determined in the test. The results are shown in Fig. 4. Closed-Circuit Test.
