Nickel Sulfide Flotation

Nickel Sulfide Flotation

copper-nickel sulphide ores is stage-wise flotation. The first flotation stage concentrates mainly copper minerals. The copper middling is re-floated to obtain nickel concentrate. During the industrial process of copper-nickel ore, it was observed that significant amount of nickel sulphides was lost to the tailings during the nickel flotation.

  • Effect Of Oxygen And Microcracking On The Flotation

    One of the difficult challenges for the nickel sulfide ores processing is the separation of pentlandite from pyrrhotite [1]. One of the difficult challenges for the nickel sulfide ore is the presence of violarite and magnetite . The conditioning of sulphide ore flotation begins with a grinding process and ends in a flotation cell at the moment a

  • Flotation Behavior Of Jinchuan High Grade Coppernickel

    The useful minerals of Jinchuan high-grade copper and nickel suphfide ores were mainly nickel and copper, whose grade were respectively 1.42% and 1.01%. The content of MgO and SiO2, main gangue components, reached 57.89%. The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively, therefore, the effects of different kinds of regulators on ...

  • The Effect Of A Novel Depressant On The Separation Of Talc

    Keywords: Sodium alginate, talc, copper –nickel sulfide, polysaccharide depressant, flotation . 1. Introduction Talc is a layered hydrous magnesium silicate in which the layers are held together by van der Waals bonds. During grinding, two different surfaces are formed. Basal cleavage planes are formed by rupture of van der Waals bonds.

  • The Beneficiation Process Of Nickel Orecoppernickel

    Sep 24, 2020 When flotation of copper sulfide nickel ores, collectors and foaming agents for flotation of copper sulfide minerals are often used. A basic principle for determining the flotation process is that it is better to allow copper to enter the nickel concentrate, and to avoid nickel entering the copper concentrate as much as possible.

  • Extracting Metals From Sulfide Ores

    As with flotation, dissolution is a corrosion-type process in which anodic oxidation of the sulfide transfers electrons to the remaining mineral and these electrons are returned to the solution by the cathodic reduction of oxygen. Nickel is recovered from the solution in the Sherritt-Gordon process either by electrolysis or by reduction with ...
