copper flotation process xinhai,jul 20, 2021 the flotation process has a relatively simple flow and has the strong adaptability to the change of ore grade. application the flotation process is generally used for copper-lead-zinc sulfide ores with simple composition, high raw ore grade, large difference in floatability of useful minerals and coarse disseminated particle size..list of solvent used in nickel flotation,mar 26, 2019 selective copper nickel flotation. bulk flotation an efficient procedure for nickel recovery is to combine copper sulphate to activate pentlandite with guar gum to depress talc. this is the method which has been used for the flotation of nickel ores in industry and which we have termed the standard bulk float..

  • The Critical Role of Pulp Density on Flotation Separation

    The Critical Role Of Pulp Density On Flotation Separation

    in nickel-copper sulfide ore processing, serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment during flotation .large amounts of serpentine in the flotation concentrate reduces the effectiveness of smelting, often resulting in the imposition of smelter penalties on mineral processing companies .,the effect of oxidation on the flotation behaviour of,in the flotation process, a number of reagents are seen as a means ofdepressing pyrrhotite. however, the complex surface chemistry of the nickel-copper ores appears to challenge the effectiveness and consistency of these reagents in many cases, testing indicates that pyrrhotite continues to float when it is not supposed to.
